Why does the bowling ball slow down after striking the pins. Check all that apply. (short answer question)

• transfers energy to the pins so it doesn't have as much

• it cannot move as fast so it slows down

• the bowling ball wouldn't slow because it's still moving

• the bowling ball gets faster when it hits the pins

How does gear protect a football player?

• it blocks sunlight from reaching sensitive skin.

• It absorbs some of the energy from collisions.

• It creates a safe zone where no players can enter.

• It slows down other players so they do not hit hard.

The kinetic energy of an object depends on _____ and _______.

• length; direction

• volume; height

• mass; speed

• temperature; shape

• it should be made of fleece

• cause the player to get hotter and overheat

• absorb energy to keep away from players bodies

• causes the players to stay cool and not overheat
