What is gravity? The force of attraction between any two bodies or particles in this universe is called gravitation and the attraction of the earth on any other body is called gravity.

Explain uniform acceleration with an example? If the rate of increase of velocity of a moving body in a particular direction is maintained constantly all the time, then the acceleration is said to be uniform. An example of uniform acceleration is the acceleration of a freely falling body due to gravity. The acceleration of a … Read more

What is the average speed? If a body does not move with a uniform speed, then the speed obtained by dividing the total distance traveled by time is called average speed.

What is gravitation? The force of attraction between any two bodies or particles in this universe is called Gravitation.

Suppose a ripe mango is falling down from the tree. Explain whether its velocity will change or not? When a mango falls down from a tree its velocity will change. When the mango was in the tree its velocity was zero. When the mango starts to fall from the tree its velocity starts to increase. … Read more

Gravity is one kind of gravitation- explain. Every particle of this universe is attracted towards each other. If one of them is earth then this attraction is called gravity, that is the attraction of the earth on any other body is called gravity. So we can say that in this universe the attraction between any … Read more

What is Motion? When a body is continuously changing its position with respect to the surroundings, then we say that the body is in motion. What is speed? The quantity by which we can measure how fast a body moves or distance traveled, is called speed. What is a scalar quantity? Physical quantities which can … Read more

What is average velocity? If a body does not move with uniform velocity, then the velocity obtained by dividing the total displacement by time is called average velocity.
