Annie has a soccer ball and a kickball. She kicks each ball with the same force. The soccer ball accelerates at 3 m/s2, and the kickball accelerates at 5 m/s2.Use Newton’s laws to describe why the kickball has a greater acceleration.
According to Newton's second law, force equals mass times acceleration (Fma). When the same force is applied to two objects, the object with the smaller mass will experience a greater acceleration. Since the kickball has a greater acceleration (5 m/s2) compared to the soccer ball (3 m/s2), the kickball must have less mass than the soccer ball.
