Question

Which object has more KE? Ball A is twice as massive as Ball B, but Ball B is moving twice as fast?

Answer 1

To ansewr this we are going to use the KE formula

$KE=\frac{m}{2}\cdot v^2$

As we see, the speed has a higher impact on the formula, it mean that if we double the mass, we would get the double of KE. But if we double the speed we would get four times KE.

The objective with double speed has a higher KE
