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.

Answer:

According to Newton’s second law (F=ma), acceleration is inversely proportional to mass when force is constant. Since Annie applies the same force to both balls and the kickball has a higher acceleration (5 m/s²) than the soccer ball (3 m/s²), the kickball must have less mass than the soccer ball.
