Newton's Laws

Front

What is Newton's First Law of Motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an external force.

Front

What does the formula F=ma represent?

Back

It represents the relationship between force (F), mass (m), and acceleration (a).

Front

If a force of 26 N is applied to two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration?

Back

The ball with a mass of 0.52 kg will have the greatest acceleration.

Front

What happens to an object at rest if no outside forces are applied?

Back

It will stay at rest.

Front

If two forces are in the same direction, do they cancel each other out?

Back

No, they do not cancel each other out.

Front

What is the net force if two forces of 20 N and 25 N are acting in the same direction?

Back

The net force is 45 N.

Front

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

Back

True.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms.

Front

What is force?

Back

Force is a push or pull on an object, measured in Newtons (N).
