A wagon is pushed and begins to move. As the wagon moves, it slows and comes a stop. What force causes the wagon to stop?
The force of gravity which is acting in the same direction as the arrow
The force of friction which is acting in the same direction as the arrow
The force of gravity which is acting in the opposite direction as the arrow
The force of friction which is acting in the opposite direction as the arrow
What type of force do you see in this video?

Students drop the same heavy ball onto identical blocks of soft clay from different heights. For each height they measure the depth of the dent the ball makes in the clay. Why is the depth of the dent different in each trial?
The size of the ball changes.
The material of the ball changes.
The mass of the ball when it hits the clay changes.
The force of the ball when it hits the clays changes.
Which change will reduce the amount of force needed to move the masses?
Decrease the height of the ramp
Increase the height of the ramp
Add an additional mass
