उत्तर
The kinetic energy of a given body depends on the momentum.
Explanation:
Kinetic energy is the energy of motion and is mathematically defined as half the product of an object’s mass and the square of its velocity. Momentum is defined as the product of an object’s mass and velocity; since velocity is a key component of both formulas, kinetic energy directly depends on an object’s momentum.
