Question

katie sits on the ground and reaches hands on a bowling ball in front of her. she uses all her force to push the ball away from her body. next, katie places her hands on a soccer ball situated in front of her at the same location. she uses all her force to push the soccer ball away from her body. how does the movement of the two balls contrast? a the soccer ball moves a greater distance because more force is acting on it. b the soccer ball moves a greater distance because it has less mass. c the bowling ball moves a greater distance because it has more mass. d the bowling ball moves a shorter distance because less force is acting on it.

Explanation:

Según la segunda ley de Newton ($F = ma$, fuerza igual a masa por aceleración), con la misma fuerza aplicada, un objeto con menor masa tendrá una mayor aceleración. El balón de fútbol tiene menos masa que el保龄球. Entonces, con la misma fuerza aplicada por Katie, el balón de fútbol se acelerará más y se moverá una distancia mayor.

Answer:

B. The soccer ball moves a greater distance because it has less mass.
