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 depends on the net force acting upon it and the object's mass, expressed as 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

Give an example of Newton's 1st Law of Motion.

Back

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

Front

Give an example of Newton's 2nd Law of Motion.

Back

If you push a car and a bicycle with the same force, the bicycle will accelerate more because it has less mass.

Front

Give an example of Newton's 3rd Law of Motion.

Back

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

Front

What does the term 'net force' mean?

Back

Net force is the total force acting on an object after all the individual forces are combined.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F=ma).
