Newton's Three Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

What does inertia mean?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is required to change the motion of an object?

Back

An unbalanced force is required to change the motion of an object.

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).

What is an example of inertia in everyday life?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it is harder to change its motion.

Front

What happens to a moving object when no unbalanced forces act on it?

Back

It will continue to move in a straight line at a constant speed.

What is an example of Newton's First Law?

Back

A soccer ball will not move until a player kicks it.

Front

What is an example of Newton's Second Law?

Back
