Newtons Three Laws of Motion Flashcard

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. It can be expressed with the formula F = ma (Force = mass x acceleration).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is how much matter is in an object, while weight is the gravitational pull on that object.

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

Give an example of Newton's 2nd Law of Motion.

Back

A small car accelerates faster than a large truck when the same amount of force is applied.

Front

Give 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 is inertia?

Back

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

Front

How does mass affect weight?

Back

Weight increases as mass increases because weight is the force of gravity acting on mass.

Front

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

Back

It continues to move at a constant velocity.
