Identifying 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. This is often expressed as the formula F = ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

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

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

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

Back

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

Front

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

Back

A soccer player can kick a lighter ball farther than a heavier ball with the same force.

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.

Front

What does 'unbalanced force' mean?

Back

An unbalanced force is a force that causes an object to change its state of motion.

Front

How does friction relate to Newton's 1st Law?

Back

Friction is an unbalanced force that opposes motion, causing moving objects to eventually stop.

Front

What is inertia?

Back

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