Newton's Review

Front

What is Newton's Second Law of Motion?

Back

The net force acting on an object is equal to the mass of the object multiplied by its acceleration (F_net = ma).

Front

What is Friction?

Back

A force that opposes the motion of two surfaces sliding past each other.

Front

How do you calculate net force when two forces act in the same direction?

Back

Add the magnitudes of the forces together.

Front

What is Force?

Back

A push or pull acting on an object.

Front

What is the formula for calculating net force?

Back

F_net = F1 + F2 (if in the same direction) or F_net = F1 - F2 (if in opposite directions).

Front

What does it mean for forces to be balanced?

Back

The net force is zero, meaning there is 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 the unit of force?

Back

Newton (N).

Front

What happens to an object's motion if the net force acting on it is not zero?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
