Question

Assertion: A light body and heavy body have same momentum. Then they also have
same kinetic energy.
Reason: Kinetic energy does not depend only on mass of the body.
Which points are true Nd which are false​

Answer 1

Answer:

The assertion and reason both are false.

Explanation:

momentum = mass × velocity

i.e. p = mv kinetic energy = (1/2) × mass × (velocity)2

i.e. KE = (1/2)mv2 = (p2 / 2m)

Kinetic energy is a function of the mass of a body and even though momentum is the same as kinetic energy is a function of the mass of a body.
