Newton's Laws of Motion Review

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is net force?

Back

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

Front

What happens when forces are balanced?

Back

The object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

The object will accelerate in the direction of the net force.

Front

What is inertia?

Back

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

Front

What is an example of balanced forces?

Back

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

Front

What is an example of unbalanced forces?

Back

A soccer ball being kicked, where the force of the kick is greater than the opposing forces.

Front

How does mass affect acceleration?

Back

The greater the mass of an object, the less acceleration it will have for a given force.
