Newtons Laws of Motion

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 are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

What happens when two boys pull a rope with equal force?

Back

They will not move at all.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration?

Back

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

Front

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

Back

A passenger lurches forward in a car when it suddenly stops.

Front

What is an example of Newton's Second Law in action?

Back

A heavier object requires more force to accelerate than a lighter object.
