Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

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

Front

What is Newton's 2nd Law of Motion?

Back

Acceleration occurs when a force acts on a mass. The bigger the mass of the object, the bigger the amount of force needed to accelerate the object.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What does the equation F=ma represent?

Back

Newton's 2nd Law of Motion.

Front

What is inertia?

Back

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

Front

Give an example of Newton's 1st Law of Motion.

Back

A soccer ball will not move until a player kicks it.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F=ma).

Front

How does mass affect acceleration?

Back

The greater the mass of an object, the more force is needed to accelerate it.

Front

What happens when two ice skaters push off each other?

Back

They both move in opposite directions due to Newton's 3rd Law of Motion.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion.
