Two pieces of paper that are the same size and mass are dropped at the same time from the top of the ladder. One is flat and the other crumpled into a ball. Which piece of paper will hit the ground first?

• The crumpled ball of paper will hit the ground first.

• The smooth, flat piece of paper will hit the ground first.

• Both pieces of paper will hit the ground at the same time.

• More information is needed to determine which ball will hit the ground first.

Two pieces of paper that are the same size and mass are dropped at the same time from the top of the ladder. One is flat and the other crumpled into a ball.Fill in the blank to explain why the crumpled paper will hit the ground first. The crumpled paper will hit the ground faster because there is less (a)   resistance from the surface slowing its motion.

Two balls that look exactly the same but have different masses are dropped at the same time from the top of the ladder. Which ball will hit the ground first?

• The ball with more mass will hit the ground first.

• The ball with less mass will hit the ground first.

• both balls will hit the ground at the same time.

• More information is needed to determine which ball has more kinetic energy.

Two balls that look exactly the same but have different masses are dropped at the same time from the top of the ladder. Fill in the blank to explain why both balls will fall at the same rate. The balls should fall at the same rate even if they have different masses because the acceleration of (a)   is constant.
