Which of the following objects has the greatest kinetic energy
A-a baseball flying through the air at 90 mph
B- a baseball flying through the air at 45 mph
C- a baseball flying through the air at 20 mph
D-a baseball sitting on the ground
Kinetic energy is the energy of an object that is moving, so D is immediately out as it is potential energy. A baseball flying at 90 mph has the greatest amount of kinetic energy because it has a higher speed.
