the ball moved faster but not as far when Joe kicked it
the ball moved faster and farther when Tom kicked it
the ball moved faster and farther when Joe kicked it.
the ball moved slower but farther when Tom kicked it
A ball is kicked across a sidewalk and onto a road covered in small rocks. Which best describes the effect the rocky road will have on the ball?
the rocky road will decrease the speed of the ball because of its mass
the rocky road will increase the speed of the ball because of it mass
the rocky road will increase the speed of the ball because of friction
the rocky road will decrease the speed of the ball because of friction

Two balls of similar shape and size, one weighing 1 pound and the other 2 pounds are both dropped from the top of a ladder at the same time. Which ball will hit the ground first?
Gravity will cause both to hit the ground at the same time
friction will cause both to hit the ground at the same time
the 2 kg ball will hit the ground first because it has more mass than the 1 kg ball
the 1 kg ball will hit the ground first because it has less mass than the 2 kg ball
