Newtons 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 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 mass of the object and the amount of force applied. It can be expressed as Force = Mass x Acceleration.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the formula to calculate force?

Back

Force = Mass x Acceleration.

Front

If a car has a mass of 1200 kg and accelerates at 5 m/s², what is the force?

Back

6000 N.

Front

What does friction do?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

True or False: All materials cause the same amount of friction.

Back

False.

Front

What happens to an object in motion if no force acts on it?

Back

It continues to move at a constant velocity.

Front

What is inertia?

Back

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

Front

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

Back

When a car suddenly stops, passengers lurch forward because of inertia.
