the motions of the earth

. Beneath the crust is hot rock. A ball of molten metal lies at the center of the earth. The earth ranks fifth in size among the planets. It has a diameter of about 13,000 kilometers. The earth is about 150 million kilometers from the sun. The atmosphere of the ea..

Projectile Motion - Projectile motion is an example of curved motion with constant acceleration. This is the two dimensional motion of a particle thrown obliquely into the air. The ideal motion of a cricket ball, a golf ball or a bullet is an exampl..

Imagine you are travelling in a moving train. Do you observe any change in your position with respect to your co-passengers? Is there any change of scene you view through the window? The change of scene indicates that the train is moving. That is, an object is said to be in motion if it c..

Problems involving constant speed and average speed Newton's First Law of Motion Newton's Second Law of Motion Newton's Third Law of Motion Universal Law of Gravitation Effect of gravity on an object at the surface of the Earth Applying a force ..

Uniform Circular Motion - The revolution of moon around the Earth and the revolution of an artificial satellite in a circular orbit round the Earth are examples of circular motion. Consider a particle moving with constant speed along the circumference of a ci..

The value of acceleration due to gravity on Earth is 9.8 m/s 2 . This means that when a body falls freely towards the Earth its velocity increases at the rate o..

Uniform Motion - Introduction - Mechanics, the oldest physical science, is the study of motion of objects. It is applied in calculation of the path of an artillery shell, a space probe sent from earth to Mars, etc. Everything in the universe is in motion, fro..

A particle moving along a curved path in a plane has two dimensional motion. The figure below, illustrates a two dimensional motion, where a particle moves from P (x 1 , y 1 ) to Q (x 2 , y 2 ) along a curved path. The bob oscillates along a curved path if the simple pend..
