Balance and Unbalance Forces Flashcard

Front

What are balanced forces?

Back

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

Front

Give an example of balanced forces in real life.

Back

Pushing a stationary box with equal force from both sides, causing it to remain in place.

Front

What are unbalanced forces?

Back

Forces that cause a change in an object's motion or shape.

Front

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

Back

There is no change in motion.

Front

How do unbalanced forces affect an object's motion?

Back

They cause the object to accelerate, change direction, or change shape.

Front

What is the effect of balanced forces on speed?

Back

Balanced forces do not change the speed of an object.

Front

Describe the direction of unbalanced forces.

Back

Unbalanced forces are not equal in size and can act in the same or opposite directions.

Front

What is an example of unbalanced forces in action?

Back

A person pushing a car that is stuck; the force from the person is greater than the friction holding the car.

Front

What is the net force when balanced forces act on an object?

Back

The net force is zero.

Front

Can balanced forces change an object's shape?

Back

No, balanced forces do not change an object's shape.
