Forces & Motion

If forces of the same strength are acting on an object in such a way that the object does NOT move, the object is said to be

• in equilibrium

• doing work

• in free fall

• dynamic

Which statement about the movement of an object with zero acceleration is true?

• The object must be at rest.

• The object must be slowing down.

• The object may be speeding up.

• The object may be in motion.

A push or pull best describes the term

Magnetic force is strongest at a magnet's

Acceleration due to gravity is approximately 9.8m/s^2. This suggests that ALL objects, no matter their mass, will fall freely from the same point above the Earth's surface at the SAME acceleration.

• True

• False

If the NORTH side of a magnet comes in contact with the NORTH side of another magnet, will the magnets attract or repel?

If the SOUTH side of a magnet comes in contact with the NORTH side of another magnet, will the magnets attract or repel?

A 200 N box is sitting on a table. Therefore, the table must be exerting a force of __________ N in order to hold the box in place.

What force opposes motion and can slow or stop a rolling object?

The object in the graph represented by the line is moving with
