Question

An object is in linear motion. If its mass reduced by 50% and its velocity increased by 4 times of its original velocity. Then which of the following is the correct relation between the original momentum P, and the final momentum P, of the object?​

Answer 1

It depends on two variables – velocity and mass of an object. There is a relation between kinetic energy and momentum as both the properties are linked with velocity. Momentum gets expressed as a multiplication of velocity and mass, whereas kinetic energy is the product of the square of speed and half of the mass.
