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 with the same speed and in the same direction unless acted upon by an unbalanced 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 = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is inertia?

Back

The resistance of an object to any change in its motion.

Front

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

Back

A magician pulls a tablecloth out from under dishes without moving them.

Front

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

Back

A heavier object requires more force to move than a lighter object.

Front

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

Back

A swimmer pushes water back with her arms, causing her body to move forward.

Front

What is the formula for calculating force?

Back

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

Front

What does the term 'net force' mean?

Back

The total force acting on an object after all the forces are combined.

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the same force is applied.
