Newton's Laws

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 an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the force exerted on it and its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is friction?

Back

A force that opposes motion between objects that are touching.

Front

Give an example of Newton's 1st Law in everyday life.

Back

A book on a table remains at rest until someone picks it up.

Front

Give an example of Newton's 2nd Law in everyday life.

Back

Pushing a shopping cart harder makes it accelerate faster.

Front

Give an example of Newton's 3rd Law in everyday life.

Back

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

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What does 'mass' refer to in physics?

Back

The amount of matter in an object, usually measured in kilograms.

Front

What does 'acceleration' mean?

Back

The rate of change of velocity of an object, measured in meters per second squared (m/s²).
