What happens when two forces act in the same direction?

Back

An object at rest stays at rest, and an object in motion stays in motion.

Front

What is the effect of unbalanced forces on an object?

Back

It causes the object to accelerate in the direction of the net force.

Front

If a 10 N force acts to the right and a 5 N force acts to the left, what is the net force?

Back

5 N to the right.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is gravitational force?

Back

The force of attraction between two masses.

Front

What is the formula for calculating net force?

Back

Net Force = Sum of all forces acting on an object.

Front

What is inertia?

Back

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