Question

1. in soccer, players kick a soccer ball across a flat field. at practice one day, three soccer balls that have th were rolling across the field. they were each kicked by a soccer player, but not from the same direction. ea changed speed as a result of being kicked. use the information in the diagram to answer.

which soccer ball(s) experienced the strongest force when it was kicked? how do you know?
a the purple soccer ball because it has the fastest ending speed.
b the blue soccer ball because it takes a stronger force to slow something down than to speed so
c the blue soccer ball because it changed speed the most.
d the purple and yellow soccer balls because they gained force, while the blue soccer ball lost fo

Explanation:

According to Newton's second law of motion, force is related to the change in momentum (which is mass times the change in velocity). Assuming the mass of the soccer balls is the same (as they are all soccer balls), the ball with the greatest change in speed (velocity) experiences the greatest force. Option c correctly states that the blue soccer ball changed speed the most. Option a is incorrect because ending speed alone doesn't determine force (initial speed also matters for the change). Option b is a false statement - the force magnitude depends on the change in speed (acceleration), not on whether it's speeding up or slowing down. Option d is wrong as force is about the change in motion (speed change) not just "gaining" or "losing" force (a mis - understanding of the concept).

Answer:

C. The blue soccer ball because it changed speed the most.
