D. Momentum

Answer 2

Answer:

The product of force and velocity is called power.

Explanation:

• Force is defined as the pull or push that changes or tends to change the state of a body. It's SI unit is Newton and measured as,

$force = mass \times acceleration....eq.i$

• Velocity is defined as the distance travelled by a body per unit time. It's SI unit is m/s and measured as,

$velocity = \frac{distance}{time} ....eq.ii$

• Power is defined as the rate of workdone. It's SI unit is Watt and measured as,

$power = \frac{workdone}{time} ....eq.iii$

On multiplying force and velocity and equating with power, we get

Power=force×velocity

Power=workdone/distance×distance/time (Since, workdone=force × distance)

Power=workdone/time

Therefore, power is the product of force and velocity.
