2.
FLASHCARD QUESTION
Front
Define balanced forces.
Back
Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no net force and no change in motion.

What is an unbalanced force?
Back
An unbalanced force occurs when the total force acting on an object is not zero, causing the object to accelerate in the direction of the net force.
