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 the formula to calculate force according to Newton's 2nd Law?

Back

Force (F) = Mass (m) x Acceleration (a) or F = m x a.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What does Newton's 3rd Law of Motion state?

Back

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

Front

What is the unit of mass?

Back

The unit of mass is the kilogram (kg).

Front

If a 10 kg object is accelerating at 2 m/s², what is the force acting on it?

Back

Force = 10 kg x 2 m/s² = 20 N.

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, for a given force, acceleration decreases.

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 3rd Law in action?

Back

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