Balanced and Unbalanced Forces

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

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

Back

The object will change its motion, either speeding up, slowing down, or changing direction.

Front

What is the net force when forces are balanced?

Back

The net force is zero when forces are balanced.

Front

Can an object be in motion and still have balanced forces acting on it?

Back

Yes, an object can be moving at a constant speed in a straight line with balanced forces acting on it.

Front

What is an example of balanced forces in everyday life?

Back

A book resting on a table experiences balanced forces: the weight of the book downward is balanced by the normal force of the table upward.

Front

What is an example of unbalanced forces in everyday life?

Back

A car accelerating when the driver presses the gas pedal experiences unbalanced forces.

Front

What is the effect of balanced forces on an object's motion?

Back

Balanced forces do not change the object's motion; it remains at rest or continues moving at a constant speed.

Front

What is the effect of unbalanced forces on an object's motion?

Back

Unbalanced forces cause an object to accelerate, decelerate, or change direction.

Front

What is the relationship between force and motion?

Back

Forces cause changes in motion; unbalanced forces result in acceleration, while balanced forces maintain motion.
