Newtons 3 Laws Review

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 the Law of Inertia?

Back

The Law of Inertia is another name for Newton's 1st Law, stating that objects resist changes in their state of motion.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

If an object is pushed with a force of 10N to the right and friction opposes it with 4N, what is the net force?

Back

6N to the right.

Front

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

Back

It continues to move at a constant velocity.

Front

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

Back

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

Front

What is an example of Newton's 3rd Law in everyday life?

Back

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

Front

What is the effect of gravity on falling objects?

Back

Gravity pulls objects downward, causing them to accelerate towards the Earth.
