Newton's Laws Flashcard (graded)

Front

What is Newton's 1st 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 Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = m × a)

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What does 'net force' mean?

Back

The sum of all forces acting on an object.

Front

What is inertia?

Back

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

Front

Give an example of Newton's 1st Law of Motion.

Back

A book resting on a table will stay at rest until someone pushes it.

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = m × a)

Front

What happens to a moving object when no net force acts on it?

Back

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

Front

What is an example of Newton's 2nd Law of Motion?

Back

If you push a shopping cart, it accelerates faster if it is empty than if it is full.

Front

What is an example of Newton's 3rd Law of Motion?

Back

When you jump off a small boat, the boat moves backward.
