- AForce
- ✓Motion
- CRoughness
- DAll the above
✓
Answer
Correct option: B.
Motion
The kinetic energy of a body is the energy by virtue of its motion.
This is the definition of kinetic energy.
If it has motion then it will have velocity,
hence kinetic energy exists.
$\text{K.E}=\frac{1}{2}\text{mv}^2$
