MCQ
The K.E. of a body can be increased maximum by doubling its:
- AMass
- BWeight
- CSpeed
- DDensity
✓
Answer
- Speed
Explanation:
$\text{K.E}=\frac{1}{2}\text{mv}^2$
$\text{K.E}\propto\text{m}\text{ &}\text{ K.E}\propto\text{v}^2$
So doubling mass will double the kinetic energy and doubling speed will make kinetic energy 4 times.
