Balanced and Unbalanced Forces Flashcard

Front

What is a balanced force?

Back

A balanced force occurs when the net force acting on an object is zero, meaning the object does not move or remains at rest.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate or change its motion.

Front

What is net force?

Back

Net force is the sum of all forces acting on an object, taking into account their directions.

Front

How do balanced forces affect the motion of an object?

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 the motion of an object?

Back

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

Front

What is an example of a contact force?

Back

An applied force, such as pushing a box, 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 on objects without physical contact.

Front

What happens to an object when two equal forces act on it in opposite directions?

Back

The object remains stationary because the forces are balanced.

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 balanced and unbalanced forces?

Back

Gravity is a force that can create unbalanced forces when it acts on an object, causing it to fall or accelerate.
