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 is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

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

How do you calculate acceleration?

Back

Acceleration = Force / Mass.

Front

What happens to an object when no net force acts on it?

Back

It will maintain its current state of motion, either at rest or moving at a constant velocity.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If a 50 N force is applied to a 500 g object, what is its acceleration?

Back

100 m/s².

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the force remains constant.

Front

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

Back

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