Newton's Laws

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

Acceleration is produced when a force acts on a mass. The greater the mass of the object being accelerated, the greater the amount of force needed.

Front

What is Newton's third law of motion?

Back

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

Front

What are the SI units for force?

Back

Newtons (N)

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What does acceleration mean?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is inertia?

Back

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

Front

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

If you push a shopping cart, it accelerates more if it is empty than if it is full.

Front

What is an example of Newton's third law?

Back

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