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 a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the net force acting on it and its mass, expressed as 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 'net force' mean?

Back

The overall force acting on an object when all the individual forces are combined.

Front

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

Back

As mass increases, acceleration decreases for the same amount of force applied.

Front

Give 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

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

Back

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

Front

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

Back

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

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

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