Newtons 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

If an object is stationary, the forces acting upon it are _____________.

Back

What is inertia?

Back

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

What does the term 'net force' mean?

Back

The overall force acting on an object when all the individual forces are combined.

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.
