# Relative Motion Formula

## Relative Motion Formula

A collision between two bodies can always be described in terms of the total momentum being zero. This is the previously mentioned center-of-mass (or center-of-momentum) frame. In the collision between two bodies of the same mass, the two bodies always have equal and opposite velocities. It should be noted that the outgoing moments in this frame of reference are antiparallel rather than perpendicular. The Relative Motion Formula is necessary for solving exercise questions.

Any collection of bodies can be described in the same way in a frame of reference where the total momentum is zero. Any observer moving with any constant velocity with respect to that frame of reference will perceive Newton’s second law to be true if it is true in that frame. The Galilean relativity principle is valid because, to a moving observer, each particle in the system appears to have the same constant velocity added to its own. The accelerations of the particles interacting with each other are unaffected by this change. Because of this, it is acceptable to describe a problem from the frame at the centre of the momentum or from any other frame that is moving relative to it at a constant speed.

It is advised that students review the Relative Motion Formula regularly. Solving problems using the Relative Motion Formula is essential for gaining a thorough understanding of the reflection topic. Students can find lessons on the Relative Motion Formula on the Extramarks learning platform. All of the important formulae must be consistently revised. The Relative Motion Formula is essential for providing precise answers to questions.
