What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not cause a change in motion, while unbalanced forces do.

Front

What occurs when forces are balanced?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What occurs when forces are unbalanced?

Back

The object accelerates in the direction of the net force.

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
