Rate of work done is ________.
- AEnergy
- BPower
- CMomentum
- DImpulse
Solution & Step-by-step Explanation
Let's analyze the physical terms:
Power: The rate at which work is done or energy is transferred over time. Mathematically, P=
t
W
. Its SI unit is the Watt (W).
Energy: The capacity to do work.
Momentum: The product of the mass and velocity of an object (p=mv).
Impulse: The change in momentum produced by a force acting over a time interval (J=FΔt).
