10-23 Newtons First Law of Motion Checkup

Front

What does 'equilibrium' mean?

Back

A state of rest or balance due to the equal action of opposing forces.

Front

What forces are acting on you right now?

Back

Gravity, Friction, Magnetic force, and all of the above.

Front

What happens to a ball after it is kicked?

Back

It will continue to move until acted upon by another force.

Front

What do unbalanced forces cause?

Back

Change in speed, Change in direction, Change in shape, and all of the above.

Front

How do we know forces are balanced?

Back

The net force is zero.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is a net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What happens when the net force is not zero?

Back

The object will accelerate in the direction of the net force.

Front

What is friction?

Back

A force that opposes the motion of an object.
