Question

The product of linear momentum and velocity of a body represents:

• A. half of the kinetic energy of the body.
• B. kinetic energy of the body.
• C. twice of the kinetic energy of the body.
• D. mass of the body.

Answer 1

Answer: (C)

twice of the kinetic energy of the body.

Linear momentum$=mv$

LInear momentum $\times$ velocity $=mv\times v$

$=2\left[1/2\right(m{v}^2\left)\right]$

$=2\times$ Kinetic Energy
