Two balls , one weighing 5kg and the other weighing 1kg , are both traveling at the same speed 3m/s A. Define kinetic energy and explain why a ball rolling has kinetic energy.
B. Which ball has more kinetic energy ? Why?

Kinetic energy is an object with mass having a forward momentum, if it hits something it will have an impact force due to the kinetic energy.

B) the 5kg ball has more kinetic energy because it has a greater mass and is traveling at the same speed so it has more kinetic energy.
