Q: Name the physical quantity that is equal to the product of force and velocity.
  • A. Work
  • B. Energy
  • C. Power
  • D. Acceleration
Correct Answer: Option C - Power = work done/time Work done = Force × displacement Velocity = displacement/time Power = Force × displacement/time Power = Force × velocity Power = F ×V
C. Power = work done/time Work done = Force × displacement Velocity = displacement/time Power = Force × displacement/time Power = Force × velocity Power = F ×V

Explanations:

Power = work done/time Work done = Force × displacement Velocity = displacement/time Power = Force × displacement/time Power = Force × velocity Power = F ×V
