Newton's Laws of Motion Concepts

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 a balanced force?

Back

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

Front

What is inertia?

Back

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

Front

What is net force?

Back

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

If a 80 N force and a 35 N force act on an object in opposite directions, what is the net force?

Back
