Field Vector
A field vector is a single vector that describes the strengths and direction of a uniform vector field. For a gravitational field, the field vector is g Weight
Weight is defined as the force on a mass due to the gravitational field of a large celestial body such as the Earth Gravitational Potential Energy
Gravitational Potential Energy is the energy of a mass due to its position within a gravitational field. On a large scale GPE is defined as the work done to move an object from infinity to a point within a gravitational field Projectile

A projectile is any object launched into the air
Trajectory
The trajectory of a projectile is the path that it follows during its flight Escape Velocity
Escape Velocity is the initial velocity required by a projectile to rise vertically and just escape the gravitational field of a planet Thrust
Thrust is a force that is exerted on an object by the expulsion or acceleration of mass in one direction Uniform Circular Motion
Uniform Circular Motion is the circular motion with a uniform orbital speed Centripetal Force
Centripetal force is the force that acts to maintain circular motion and is directed towards the centre of the circle Centripetal Acceleration
Centripetal Acceleration is always present in uniform circular motion it is associated with centripetal force and is also directed at the centre of the circle Period
Period is the time taken to complete on orbit
Low Earth Orbit
Low Earth Orbit is an orbit higher than 250km and lower than 1000km Geostationary Orbit
Geostationary Orbit is an orbit where the Satellite orbits in tandem with that of earth. This corresponds to an approximate altitude of 35 800km Transfer Orbit
Transfer Orbit is a orbit used to manoeuvre a satellite from one orbit to another Ionisation Blackout
Ionisation Blackout is a period of no communication with a space craft due to a surrounding layer of ionised atoms forming in the heat of re-entry Vector

Abstract
This experiment measures the study of motion by observing the force of gravity acting solely upon an object, and also measures reaction time. If an object is in free fall, the only force acting upon it is gravity. The object used in this experiment was a golf ball that provided some acceleration when dropped. A sensor positioned underneath a table recorded the golf ball’s pattern of motion, when dropped. The main objective of performing this experiment is to measure the velocity and position of the ball to eventually find the acceleration of free fall. A computer program called, DataStudio, was used to create a graph of position vs. time and a graph of velocity vs. time. The second part of the experiment involved randomly dropping a ruler and having your partner catch it to determine reaction time.
Questions
1. The parabolic curves open upward instead of downward because of the golf balls movement over time: where it is dropped from, to where it ends up. The ball begins close to the sensor, then drops to the ground, then bounces back up closer to sensor again, therefore the bounces correspond with the bottom curves of the parabola. If the data were collected from the floor then the curve would open downward. But because the sensor graphs the position from the sensor, the curve was upwards.

...Kinematics is the branch of classical mechanics that describes the motion of bodies and systems without consideration of the forces that cause the motion. There are four activities done in this experiment, graphical analysis of human motion, where displacement vs. time and velocity vs. time were graphed. Graphical analysis of motion where in the 10th seconds the total displacement is 14.69m, average velocity is 1.47 m/s. Reaction time where one of the normal reaction time among the group is 0.4s and the reaction time while someone is distracting the member is 0.5s, and lastly graph matching.
1. Introduction
All of us have the ability to move. Knowing how to describe motion is an important first step in understanding the underlying physics that governs changes in motion. We see changes in motion all the time, as we go to work or school, participate in sports or even wander around our homes. If we never changed our own motion, we would never make it out of bed in the morning. The study of motion and of physical concepts such as force and mass is called Dynamics. Kinematics is one of the topics under dynamics. Kinematics describes motion without regard to its causes. In this experiment, kinematics focuses in one dimension: a motion along a straight line. This kind of motion, involves velocity, displacement, and acceleration with regards to time. The objectives of the experiment are to draw the displacement versus time graphs and velocity versus time graphs...

...Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist, and the first Greek philosopher. He was an astronomer, merchant and mathematician, and after visiting Egypt he is said to have originated the science of deductive geometry. He also discovered theorems of elementary geometry and is said to have correctly predicted an eclipse of the sun. Many of his studies were in astronomy but he also observed static electricity. Phythogoras was a Greek philosopher. He discovered simple numerical ratios relating the musical tones of major consonances, to the length of the strings used in sounding them. The Pythagorean theorem was named after him, although this fundamental statements of deductive geometry was most likely first an idea from Egyptian methods of measurements. With the help of his followers he discovered that the earth was a sphere, but he did not believe it revolved around the sun. Democritus was the leader of a group called Atomists. Although they were unable to prove that matter was made up of small particles, they...

A New Look at Sports
Growing up in a family filled with athletic desire to be great at whatever sport we would participate in and understanding simple physics in Cosmetology, I never realized how much physics comes into play when playing sports. We don’t call it physics when were playing, football, basketball, baseball because it’s just a natural feeling when were throwing a ball or trying to tackle someone. When we began to learn about Newton’s law of Gravity. All sports in the world today have all displayed many aspects of force, motion, gravity, distance and speed but we don’t take the time to realize actually what were doing. Sports have been a big part of my life ever since I was able to stand but I never have once stopped and asked why? Why does a person have tackle with such force and such speed to be able to bring down the runner, or why a baseball can be hit with such force off a bat to be able to hit a home run. Sports are filled with physics that no one understands because we never take the time to ask why, sports are all about physics and the techniques we use to be great at a sport.
When I started to think about all the sports I have played in my life and ask why things happened the way they do I started with the first sport I fell in love with. Baseball was one of the sports that I have always had such a...

...Student Exploration: Fan Cart Physics
Vocabulary: acceleration, force, friction, mass, newton, Newton’s first law, Newton’s second law, Newton’s third law, velocity
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. Imagine a horse pulling a cart. What would happen to the speed of the cart if several bags of cement were added to the cart? The speed of the cart would decrease.
2. Suppose several more horses were hitched up to the same cart. How would this affect the speed of the cart? This would affect the speed of the cart because there is more force pulling the positive direction.
Although these questions may seem simple, they form the basis of Newton’s second law of motion. The Fan Cart Physics Gizmo™ can be used to illustrate all three of Newton’s laws.
Gizmo Warm-up
The Fan Cart Physics Gizmo™ shows a common teaching tool called a fan cart. Place fan A on the cart and turn it on by clicking the ON/OFF button below.
1. Look at the blue lines coming from the fan. In which direction is the air pushed? Negative
2. Press Play ([pic]) and observe the cart. In which direction does the cart move? positive direction
By blowing to the left, the fans exert a force on the cart that pushes it to the right. This illustrates Newton’s third law: A force in one direction results in an equal force in the opposite direction.
3. The velocity (v) of the cart is its speed and direction. Click Reset...

...(almost) every student. This study aimed to determine whether a chosen subject is tougher than another. This study focused on the students of Mapúa and subjects such as Mathematics and Physics. This study would then suggest where students need to focus their study between the said subjects.
Definition of Terms
Mathematics is the science of numbers and their operations, interrelations, combinations, generalizations, and abstraction and of space configurations and their structure, measurement, transformations, and generalizations.
Calculus is a branch of mathematics focused on limits, functions, derivatives, integrals, and infinite series. This subject constitutes a major part of modern mathematics education. It has two major branches, differential calculus and integral calculus, which are related by the fundamental theorem of calculus. Calculus is the study of change, in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations.
A differential equation is a mathematical equation for an unknown function of one or several variables that relates the values of the function itself and its derivatives of various orders. Differential equations play a prominent role in engineering, physics, economics, and other disciplines.
Physics (from Greek: φύσις physis "nature") is a natural science that involves the study of matter and its motion through...

NOTES
When an object changes its position in respect to a point and time, that’s motion. Force is what changes the motion of an object with mass and modifies its velocity.
Note that force can act at a distance. Magnetism is a type of non-contact force. Friction in the other hand only operates in contact of objects, those are called contact forces.
An object initially at rest is predicted to remain at rest if the total force acting on it is zero, and an object in motion remains in motion with the same velocity in the same direction.
The force needed to accelerate an object equals the mass of the object multiplied by its acceleration. Best known as Force = Mass x Acceleration
"For every action there is an equal and opposite reaction. To understand this law you must understand action-reaction pairs.
"For every action there is an equal and opposite reaction. To understand this law you must understand action-reaction pairs.
OBSERVATIONS
The motion of an object can be described by its speed, direction, and motion. Note that an object that no force is applied to, will continue to move at a constant speed straight. If multiple forces act upon an object within a straight line, then the forces will reinforce or cancel one another depending of factors such as magnitude and direction. Unbalanced...
