The results of this lab reflect on the different kind of elevators. The mass is constant as if your not doing anything to change it. We feel heavy in a elevator because the accelerator is going up with an acceleration and not when it is going up with uniform speed. That is due to the force that we may experience from the floor of the elevator on our feet.

Law of Acceleration

- The acceleration a of a body is parallel and directly proportional to the net force F acting on the body, is in the direction of the net force, and is inversely proportional to the mass m of the body, i.e., F = ma.

The Atwood Machine

- is a device where two masses, M and m, are connected by a string passing over a pulley.

Theory

- the atwood machine was invented in 1784 by Rev. George Atwood as a laboratory experiment to verify Newton’s laws of motion. The ideal atwood machine consists of two masses m1 and m2, connected by an inelastic massless string over an ideal massless pulley

- when m1=m2, the machine is in neutral equilibrium regardless of the position of the weights.

- When m2>m1 both masses will experience uniform acceleration.

Conclusion:

The goal of this experiment was to determine the acceleration due to

gravity on earth. We assumed that our result would be 9.8m/s^2, because

that is accepted for the value of g.

I therefore conclude that, the friction between string and pulley is

there when masses are added to m2, the system still remains balanced. To

determine the proper amount of friction in terms of added masses, one

should add a small amount of mass to m2 until the system...

...Experiment 3.1 Newton’s SecondLaw of Motion Aim: To investigate the relationship between net force, mass and acceleration Hypothesis: Since Newton’s secondlaw of motion states that the acceleration of an object is directly proportional to the total force acting upon that object, we can assume that the more mass being pulled down on the cart the greater the acceleration of it will be and therefore the greater its net force will be. Apparatus: Wheeled carts Pulleys Balance Ticker Tape Weights String Factors affecting Acceleration of Cart: Mass of Weights pulling down the cart Friction of cart wheels along the ground Mass of the cart Length of the String to the pulley Friction of sting against the pulley Independent Variables: Mass of Pulley Mass of Trolley Dependent Variables: Acceleration Net force Total Mass Results {draw:frame} {draw:frame} Discussion The Cart went faster when it had 105 grams of weights pulling down on it compared to when it had 5 grams of weight pulling on it, thus proving my hypothesis. Just by putting an extra 100 grams of weight pulling down on the cart acceleration was around 3.8 times faster than previously and so force also increased by a scale factor of that amount. We can assume that another extra 100 grams of weight pulling down on the cart would...

...Newton’s secondlaw of motion (Car vs Suv)
According to newton’s secondlaw of motion, Acceleration is produced when a force acts on a mass. The greater the mass is, the grater the acceleration is needed to move forward. This law basically states that a force applied to the objects changes its velocity overtime in the direction of the force that is applied, the acceleration is directly proportional to the force, as an example, if pushing on an object, causing it to accelerate, and then you push, the same object three times harder, the acceleration will be three times greater and the acceleration is inversely proportional to the mass of an object, if you push equally on two objects, and one of the objects has five times more mass than the other, it will accelerate at one fifth of the object.
SUV’s have the greater mass than the car. So SUV’s need more force than light car to move forward in the direction the force is applied, we can say that SUV’s need more force to act than a car, for example driving an SUV and light car at the same velocity, the force needed for car would be less than the SUV and the car would run faster than a suv as it need less force than an SUV. SUV requires more fuel than a normal car. A Car could run faster than an SUV and it even requires less fuel. Therefore, the more mass the object has, it requires more force to make it move forward and to act...

Newton’s Three Laws of Motion
Sir Isaac Newton first introduced his three laws in 1686. Newton’s Three Laws of Motion not only improved math and science all over the world, but they played a major role in the development of human beings giving us a better understanding of the world in which we live and the laws that each and every one of us follow. Newton’s first law islaw of inertia, which is a restatement of Galileo’s idea, an object in rest stays in rest or an object in motion stays in motion unless acted upon by an outside force. Newton’s secondlaw states acceleration is proportional to the magnitude of the net force, is in the same direction, and is inversely proportional to the mass of the object. Newton’s third law, action and reaction, states for every action there is an equal and opposite reaction.
The first of Newton’s three laws is the law of Inertia. The law of inertia is, every object continues in a state of rest, or of motion in a straight line at a constant speed, unless it is compelled to change that state by forces exerted upon it. In short an object at rest stays at rest and an object in motion stays in motion unless acted upon by an outside force. There are two types...

INTRODUCTION:
Newton's laws are applied to objects which are idealized as single point masses in the sense that the size and shape of the object's body are neglected in order to focus on its motion more easily. This can be done when the object is small compared to the distances involved in its analysis, or the deformation and rotation of the body are of no importance. In this way, even a planet can be idealized as a particle for analysis of its orbital motion around a star.
Newton’s secondlaw of motion can be used conveniently to derive the equation of...

...Chapter 6 Newton’s SecondLaw of Motion-Force and Acceleration
The Big Idea: An object accelerates when a net force acts on it.
6.1 Force Causes Acceleration
• Unbalanced forces acting on an object cause the object to accelerate.
• The combination of foces acting on an object is net force; acceleration depends in net force.
• Doubling the force on an object doubles its acceleration.
• An object’s acceleration is directly proportional to the net force acting on it.
6.2 Mass Resists Acceleration
• For a constant force, an increase in the mass will result in a decrease it the acceleration.
• The same force applied to twice as much mass result is only half the acceleration.
• For a given force, the acceleration produced is inversely proportional to the mass. Inversely means that the two values change in opposite directions.
6.3 Newton’s SecondLaw
• Newton’s secondlaw states that the acceleration produced by a net force on an object is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the object.
• Newton’s secondlaw describes the relationship among an object’s mass, an object’s acceleration, and the net force on an object.
• In equation form, Newton’s...

...Newton’s SecondLaw
How does a cart change its motion when you push and pull on it? You might think that the harder you push on a cart, the faster it goes. Is the cart’s velocity related to the force you apply? Or does the force just change the velocity? Also, what does the mass of the cart have to do with how the motion changes? We know that it takes a much harder push to get a heavy cart moving than a lighter one.
A Force Sensor and an Accelerometer will let you measure the force on a cart simultaneously with the cart’s acceleration. The total mass of the cart is easy to vary by adding masses. Using these tools, you can determine how the net force on the cart, its mass, and its acceleration are related. This relationship is Newton’s secondlaw of motion.

Newton’s SecondLaw of Motion
Objective
As you are probably aware from everyday experience, heavier objects require a greater force to move around than lighter ones. Isaac Newton quantified observations like this one into what is probably the most useful expression in all physics: F = M a, otherwise known as Newton’s Law of Motion. Here, F is the net external force acting on mass M, and a is the resulting acceleration.
The primary objective for this lab is to test the conjecture that Newton’s secondLaw of Motion does apply to actual laboratory measured motions.
Introduction
The interaction between various objects is responsible for a whole variety of phenomena in our inverse. If no interactions existed, our universe would consist of a bunch of objects engaged in motion at constant velocity in accordance to Newton’s first law. We couldn’t even perceive this universe, because our perceptions are due to interactions with the external environment.
Force is a critical physical concept. While we can’t test every possible situation in which force act, we do know that Newton’s secondlaw was based on Newton’s observations that the acceleration of an object experience is directly proportional to the applied force. In equation form this is
F = Ma
Where...

...DYNAMICS
-studies the relationship of motion to the forces that causes it.
Types of Forces:
(a) Normal Force, n :When an object rests
or pushes on a surface, the surface exerts
a push on it that is directed perpendicular
to the surface.
(b) Friction Force, f : In addition to the
normal force, a surface may exert a
frictional force on a object, directed
parallel to the surface and opposite the
motion or impending motion of the
object.
f s = µ s n - static friction, maximum friction before the
object begins to move.
n
ff kk ==µµk k n - kinetic friction, friction on a moving object.
DYNAMICS
Types of Forces:
(c) Tension Force, T : A pulling force
applied on an object by any longitudinal
object. Along the longitudinal object,
tension is always directed away any point
of consideration.
(d) Compression Force, C : A pushing force
applied on an object by any longitudinal
object. Along the longitudinal object,
compression is always directed towards
any point of consideration.
(e) Weight, W : The pull of gravity on an
object. It is always directed vertically
downward.
W = mg
