Question
The kinetic energy of the body depends:
- On the mass of the body only.
- On the velocity of the body only.
- Both a and b
- Either a or b
Hint:
Kinetic energy is the energy possessed by a body in motion.
The correct answer is: Both a and b
The kinetic energy of the body depends Both mass and velocity of the body.
- A body in motion will have a velocity and a mass.
- Also, the velocity of the body can vary depending on the frame of reference.
- Kinetic energy =
(mass).(velocity)2
- K.E = mv2
