Newtons Three Laws of Motion Flashcard

Front

What is a force?

Back

A push or pull on an object.

Front

What does Newton's 1st Law of Motion state?

Back

An object in motion (or at rest) will stay in motion (or at rest) until an outside force acts upon it.

Front

What happens when a horse stops suddenly?

Back

The rider continues to move forward due to inertia, illustrating Newton's 1st Law of Motion.

Front

True or False: When a student slaps a desk, the desk exerts the same amount of force back on the student's hand.

Back

True.

Front

What occurs when an unbalanced force acts on an object?

Back

It changes the motion of the object.

Front

What is inertia?

Back

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

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.

Front

What is the formula for Newton's 2nd Law?

Back

F = ma (Force = mass x acceleration).

Front

What is an example of Newton's 3rd Law of Motion?

Back

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

Front

What does Newton's 3rd Law of Motion state?

Back

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