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.

Front

What is inertia?

Back

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

What does Newton's Second Law of Motion state?

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 the formula for Newton's Second Law of Motion?

Back

F = ma (Force equals mass times acceleration).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

What does it mean when we say the net force is zero?

Back

It means that all the forces acting on an object are balanced, resulting in no change in motion.

How does inertia affect you when an airplane takes off?

Back

You tend to fall backward because your body wants to remain at rest while the airplane moves forward.
