Balanced and Unbalanced Forces Flashcard

Front

What is a force?

Back

A force is a push or a pull on an object.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and can cause an object to move or change its motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, there is no change in motion; the object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force.

Front

What is an example of a contact force?

Back

An applied force, such as pushing a door open, is an example of a contact force.

Front

What is an example of a non-contact force?

Back

Gravity is an example of a non-contact force, as it acts at a distance.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting between surfaces in contact.

Front

What is the role of gravity in motion?

Back

Gravity pulls objects toward the Earth, affecting their motion and causing them to fall.

Front

How can you identify unbalanced forces in a situation?

Back

You can identify unbalanced forces if an object is moving or changing direction.
