Question

explain how momentum and energy are related

Answer 1

$\underline{\underline{\sf{Two \: things \: differentiate \: the \: momentum \: principle \: from \: the \: work \: energy \: :-}}}$

✰ First, it is technically a vector equation because the momentum of an object depends upon its direction of movement.

✰The work energy principle depends only on displacement, not time.

Answer 2

Explanation:

Momentum vs Energy

• Though momentum and kinetic energy of a moving object are related, they are not the same of equivalent.

• While momentum is a vector quantity requiring direction as well, kinetic energy is a scalar quantity needing only amount.

• If you double the velocity of a moving object, its momentum is doubled but the kinetic energy gets quadrupled.
