Newtons First Law of Motion Checkup

Front

What is the definition of 'equilibrium'?

Back

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

Front

How can we determine if forces are balanced?

Back

The net force is zero.

Front

What do unbalanced forces cause?

Back

Change in speed, change in direction, and change in shape.

Front

What forces are acting on you right now?

Back

Gravity, friction, and magnetic force.

Front

How does a ball move when thrown into space?

Back

It will move in a straight line indefinitely.

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 happens to an object in motion if no forces act on it?

Back

It continues to move in a straight line at a constant speed.

Front

What is a net force?

Back

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

Front

What does it mean if an object is accelerating?

Back

It is changing its speed or direction.
