• Circular Motion and Gravitation - 1366 Words
Circular Motion and Gravitation Circular motion is everywhere, from atoms to galaxies, from flagella to Ferris wheels. Two terms are frequently used to describe such motion. In general, we say that an object rotates when the axis of rotation lies within the body, and that it revolves when the axis is outside it. Thus, the Earth rotates on its axis and revolves about the Sun. When a body rotates on its axis, all the particles of the body revolve – that is, they move in circular paths...

• Newton's Law of Universal Gravitation
Newton's Law of Universal Gravitation Gravity if one of the four fundamental forces in the universe. Though the fundamental principles of it eluded scientists until Sir Isaac Newton was able to mathematically describe it in 1687 (Eddington 93). Gravity plays a serious part in everyday actions as it keeps everything on the ground; without gravity everything would be immobile unless a force was applied (then it would move infinitely because there would be no force to stop it). Perhaps, the...

Newton’s Laws of Cooling & Universal Gravitation Law’s of Cooling: Newton's law of cooling is used measure the temperature change of an object of some temperature placed in a place of a different temperature. The law states that dT/dt= k(T-R) where T is the temperature of the object at time t, R is the temperature of the surrounding of the place (constant) and k is a constant of proportionality. This law states that the rate of change of temperature is proportional to the difference...

• Sir Isaac Newton: the Universal Law of Gravitation
There is a popular story that Newton was sitting under an apple tree, an apple fell on his head, and he suddenly thought of the Universal Law of Gravitation. As in all such legends, this is almost certainly not true in its details, but the story contains elements of what actually happened. What Really Happened with the Apple? Probably the more correct version of the story is that Newton, upon observing an apple fall from a tree, began to think along the following lines: The apple is...

• Acceleration due to gravity - 1167 Words
Determination of the Acceleration Due to Gravity By A Good Student Abstract The acceleration due to gravity, g, was determined by dropping a metal bearing and measuring the free-fall time with a pendulum of known period. The measured value is 9.706 m/s2 with a standard deviation of 0.0317, which does not fall within the range of known terrestrial values. Centrifugal forces and altitude variations cannot account for the discrepancy. The calculation is very sensitive to the measured...

In a world without gravity, one would be weightless, but always nauseous. Because of this, it would be very difficult to complete a lot of your daily activities without throwing up. If you tried to eat something while you and your food are floating around, you will probably have a lot of trouble trying to hold your food down. In 0-g, life would be very hard.

Misconceptions of Physics One of the misconceptions in physics is about Newtons laws. It says that friction can't act in the direction of motion. This is wrong because friction can act in the same direction as motion simply because a car on a road is traveling in one direction. The friction on the tires causes it to slow down over a distance along with some air resistance. This proves that friction can act in the same direction as motion A misconception in physics is that the moon is not...

In Newtonian physics, free fall is any motion of a body where its weight is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and it moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain. An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards...

﻿My Solar System Name Period Introduction: Every physics student has had a lot of experience with the force of gravity. Unfortunately, this experience is limited to the interaction between a very large object, the Earth, and much smaller objects that are very close to it. This is a very limited range of the possibilities. Software simulations of gravity allow physics students to explore a variety of other gravitational interactions between objects. These activities are designed to be...

The Nature of Dark Matter We observe the universe around us through many scientific means. However it is through the electromagnetic spectrum, that is everything from radio waves to gamma waves, that we learn about the objects in our world and beyond. However we can also learn about our universe through indirect means, such as the effect of gravity on light as well as larger objects like our galaxy. In fact it is this indirect method of observation that has led us to the discovery of...

The Big Idea Over 2500 years ago Aristotle proposed two laws of physics governing motion. One for ‘Earthly bodies’ (objects on Earth) that states objects naturally go in straight lines and one for ‘Heavenly bodies’ (objects in space) that states objects naturally go in circles. This idea held steady for 2,000 years, until Isaac Newton in a triumph of brilliance declared that there is one law of physics that governs motion and he unified “earthly” bodies and “heavenly” bodies with the The...

Although the speed is constant, velocity is continually changing, since it is constantly changing its direction of motion.

• What is a period? List some precautions you should take when measuring the length and time
Pendulum is an object that, due to action of gravitational force, swings back and forth at a regular rate around a fixed point if it is pulled aside and let go. A simple pendulum consists of a weight hanging at the end of a string or wire. The path travelled by the weight is called the arc of the pendulum. The period of oscillation is the time it takes the weight to pass back and forth once over this arc. The length of the pendulum is the distance between the point at which the pendulum is...

Newton's Law of Universal Gravitation Isaac Newton compared the acceleration of the moon to the acceleration of objects on earth. Believing that gravitational forces were responsible for each, Newton was able to draw an important conclusion about the dependence of gravity upon distance. This comparison led him to conclude that the force of gravitational attraction between the Earth and other objects is inversely proportional to the distance separating the earth's center from the object's...

﻿Analysis of Data From the data we gathered on this experiment, the effects of the height of the track can greatly affect the acceleration of the cart. Base on the data on the table, the higher the height of the track will have higher acceleration and will lead to higher sinθ. From this, it implies that the higher the displacement of the track will lead to the higher acceleration of the cart. The reason why the cart will have higher acceleration to higher displacement is because of the...
