Newton's Laws of Motion Review

Front

What is an unbalanced force?

Back

Forces that produce a nonzero net force, which changes an object's motion.

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

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

Back

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

Front

What does Newton's 2nd Law of Motion state?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied (F=ma).

Front

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

Back

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

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked, causing it to move.

Front

What is an example of a balanced force?

Back

A book resting on a table, where the force of gravity is balanced by the normal force from the table.

Front

What happens to an object when unbalanced forces act on it?

Back

It will accelerate in the direction of the net force.

Front

What is the net force?

Back

The overall force acting on an object after all the forces are combined.

Front

What is inertia?

Back

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