Newton's Laws of Motion

Front

An object at rest will _______ if no outside forces are applied.

Back

Stay at rest

Front

Momentum is related to Newton's first law.

Back

True

Front

A greater applied force is required to move an object with a greater mass than one with a smaller mass.

Back

True

Front

The SI units for force are...

Back

Newtons

Front

If a baseball and a cannonball are dropped from the same height at the same time, which ball will hit the ground first?

Back

The balls land at the same time.

Front

If an action force is a cue ball (white) hitting a billiard ball (various colors) when playing pool, what is the reaction force?

Back

exerted on all the other billiard balls.

Front

Why does a crumpled piece of paper hit the ground before a flat sheet of paper?

Back

There is more air resistance against the flat paper.

Front

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

Back

remain in motion.

Front

An ice skater at rest pushes against a sled at rest, causing both the skater and sled to move away from each other with different accelerations. This is an example best described by:
- Newton’s first law of motion for objects at rest.
- Newton’s first law of motion for objects in motion.
- Newton’s second law of motion.
- Newton’s third law of motion.

Back

Newton’s second law of motion.

Front

A sled sliding on a flat, icy surface with a constant velocity is best described by:
- Newton’s first law of motion for objects at rest.
- Newton’s first law of motion for objects in motion.
- Newton’s second law of motion.
- Newton’s third law of motion.
