Balanced and Unbalanced Forces

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the motion of an object.

Front

Example of balanced forces in everyday life?

Back

Sitting in a chair is an example of balanced forces, as the force of gravity is balanced by the support force from the chair.

Example of unbalanced forces in everyday life?

Back

A boy pushing against a wall is an example of balanced forces, as the wall exerts an equal and opposite force.

Front

What happens when unbalanced forces act on an object?

Back

Unbalanced forces can change the speed or direction of an object, causing it to accelerate.

Front

What is the net force when forces are balanced?

Back

The net force is zero when forces are balanced.

Front

What is the net force when forces are unbalanced?

Back

The net force is greater than zero when forces are unbalanced.

Front

How do balanced forces affect motion?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant speed.

Front

How do unbalanced forces affect motion?

Back

Unbalanced forces cause an object to start moving, stop moving, or change direction.

Front

What is an example of unbalanced forces changing an object's motion?

Back

A car accelerating when the driver presses the gas pedal is an example of unbalanced forces changing motion.
