Force & Net Force

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is net force?

Back

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

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 and opposite, causing a change in the motion of an object.

Front

If two forces of 10N and 5N act in the same direction, what is the net force?

Back

15N

Front

If two forces of 10N and 5N act in opposite directions, what is the net force?

Back

5N in the direction of the larger force.

Front

What happens to an object at rest when balanced forces act on it?

Back

It remains at rest.

Front

What happens to an object in motion when unbalanced forces act on it?

Back

It accelerates 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

How does mass affect force?

Back

More mass means more force is needed to change the object's motion.
