Velocity

Things to remember

• The velocity of the body is the distance travelled by it in unit time to a certain direction.

• Uniform velocity: If a moving body cover the equal distance in equal interval of time , then the body is said to have uniform velocity.

• Variable velocity:If a moving body covers  the different distance in unit time then the body is said to have variable velocity.

• Relative velocity: The laws of physics which apply when you are at rest on the earth also apply when you are in any reference frame which is moving at a constant velocity with respect to the earth.
