Newton's First and Second Law Review

Front

What is a force?

Back

A push or pull.

Front

What happens to a soccer ball when a force is applied to it?

Back

It will move in the direction of the force.

Front

What is inertia?

Back

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

Front

How does mass relate to inertia?

Back

Objects with greater mass have more inertia.

Front

What will happen to a moving object if no unbalanced force acts on it?

Back

It will keep moving in a straight line.

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 is an unbalanced force?

Back

Forces that are not equal, causing a change in motion.

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 an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).
