Balanced and Unbalanced Forces

Front

What is the net force?

Back

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

Front

If forces are going in the same direction, you should:

Back

Add the forces together to find the net force.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is 0 N, and the object remains at rest or continues to move at a constant speed.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate.

Front

What is force?

Back

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

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How do you calculate net force when forces are in opposite directions?

Back

Subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

What is an example of balanced forces?

Back

A book resting on a table is an example of balanced forces; the force of gravity pulling it down is balanced by the normal force from the table pushing it up.

Front

What is an example of unbalanced forces?

Back

A soccer ball being kicked is an example of unbalanced forces; the force of the kick is greater than the friction and air resistance acting on it.

Front

What does it mean if an object is in motion with no net force acting on it?

Back

If an object is in motion with no net force acting on it, it will continue to move at a constant velocity.
