Students are practicing softball on a windy day. The pitcher throws the softball toward the batter. The students notice that the softball moves faster after it is hit by the bat than when it is thrown by the pitcher. Which statement best explains what happens to the energy of the softball when it is hit by the batter?

• When the bat hits the ball, energy transfers from the softball to the bat.

• The softball is still moving, so there is no transfer of energy to or from the softball.

• here is a transfer of energy from the softball to the bat, increasing the energy of the bat’s movement.

• There is a transfer of energy from the bat to the softball, increasing the energy of the softball’s movement.
