Newton's Laws

Front

What is Newton's First 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 Second 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 Third 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 friction?

Back

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

Front

What does it mean for forces to be balanced?

Back

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

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What is an example of Newton's First 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 Second Law in everyday life?

Back

If you push a shopping cart, it accelerates more if it is empty than if it is full.

Front

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

Back

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