What pulls a ball back to earth?

Back

Gravity

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is Newton's First Law?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

Back

mass

Front

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will ___________.

Back

remain in motion.

Front

What is the formula for Newton's Second Law of Motion?

Back

F = ma (Force equals mass times acceleration).

Front

What is inertia?

Back

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

Front

What happens to an object in motion when no external forces act on it?

Back

It continues to move at a constant velocity.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

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

Back
