Using F=ma, explain why a train is more difficult to start moving and more difficult to bring to a stop than an average sized car.
A train has more mass, requiring more force to change its motion.
A train has less mass, requiring less force to change its motion.
A train has the same mass as a car, so the force required is the same.
A train's mass does not affect the force required to change its motion.

A magician performs a trick where the tablecloth is quickly removed from the table, while all of the items on the table stay in the same place. Which statement below accurately describes the reason that the items remain on the table?
The mass of the items on the table is so small that no force was applied when the tablecloth was pulled out from under the items.
The direction of the force applied to the tablecloth was down towards the ground, so the items accelerated down towards the table until they rested on the table.
The action force of the moving tablecloth caused a reaction force from the items on the table, so the forces in the items remained balanced and the items remained at rest on the table.
The moving tablecloth did not apply much force to the items on the table, so the forces on the items remained mostly balanced allowing the items to remain at rest on the table.

Balanced
Gravitational
Frictional
Unbalanced
