Question

multiple - choice question
define power. the rate at which ______ is done.
newtons
work
displacement
rewatch

Explanation:

Power is defined in physics as the rate at which work is done. The formula for power \( P=\frac{W}{t} \), where \( W \) is work and \( t \) is time. Newtons are a unit of force (\( F = ma \), \( m \) in kg, \( a \) in \( m/s^{2} \)), and displacement (\( d \)) is related to work (\( W = F\times d\) when force and displacement are in the same direction), but power specifically focuses on the rate of work.

Answer:

B. Work
