Which chair experienced the greatest force and WHY?

• The red chair because it's going the fastest.

• The red chair because it has more mass and in order to speed up the same amount as the yellow, you'd need more force.

• The yellow chair because it has less mass.

• They experienced the same force because they both sped up by 3 m/s.

A box was slid across the floor. The box gradually slowed down and stopped after moving 3 feet. Why did the box stop moving?

• All objects stop moving because their natural state is to be still.

• The floor exerted a force that is opposite to the direction of the box's motion.

• The floor absorbs force from the box.

• The box ran out of force.

Both golf ball have the SAME mass. Which one experienced the greatest force and WHY?

• The green ball because it changed velocity the most.

• The green ball because slowing down takes more force.

• The white ball because it is going the fastest.

Why did the space pod have a higher velocity (bounce away faster) after the collision than the space station did?

• The pod and the space station both had the SAME velocity after the collision.

• The pod experienced a greater force during the collision than the space station.

• The pod has less mass so it's affected more by the force during the collision.
