Newton's Laws of Motion

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 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 = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What does the term 'force' mean in physics?

Back

A force is a push or pull on an object that can cause it to accelerate.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

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

Front

What is an example of Newton's 1st Law in everyday life?

Back

A soccer ball remains at rest until a player kicks it.

Front

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

Back

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

Front

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

Back

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