Question

why do you think your answer for question 6 has the least amount of total energy?
the other objects (another player or the ground) are bigger and have more energy.
the soccer ball is very light and has less energy than another player or the ground
all of these collisions have the same amount of energy.

Explanation:

Energy is related to mass and motion. A soccer ball has less mass compared to a player or the ground. According to the formula for kinetic energy \(E_k=\frac{1}{2}mv^2\) (where \(m\) is mass and \(v\) is velocity), if velocities are comparable, a smaller mass (\(m\)) leads to less kinetic energy. Also, the ground is a large, stationary object (for the sake of this comparison, assume it has negligible motion - related energy in this context).

Answer:

B. The soccer ball is very light and has less energy than another player or the ground.
