Question 1

Why does velocity have a bigger effect than mass?

Accepted Answer

Because velocity is squared in the formula. Doubling mass doubles energy, but doubling velocity quadruples it. This is why speed limits are so important for safety.

Question 2

What is the unit of kinetic energy?

Accepted Answer

Kinetic energy is measured in Joules (J). 1 J = 1 kg·m²/s². One Joule is about the energy of dropping an apple from 1 meter.
