Newton & Laws

Front

What is Newton's 1st Law of Motion?

Back

An object in motion tends to stay in motion, and an object at rest tends to stay at rest unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

F = ma, which means force equals mass times acceleration.

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

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

Front

What is an unbalanced force?

Back

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

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

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

Back

When a car suddenly stops, passengers lurch forward due to inertia.

Front

What happens when a cyclist crashes into a guardrail?

Back

The cyclist may fly over the handlebars due to inertia.

Front

What is the formula for calculating force?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.
