Explain how balanced and unbalanced forces affect an object’s motion differently.

• Balanced forces do not change the motion of an object, while unbalanced forces cause a change in motion.

• Balanced forces cause a change in motion, while unbalanced forces do not change the motion of an object.

• Both balanced and unbalanced forces cause a change in motion.

• Neither balanced nor unbalanced forces affect an object's motion.

Can there be forces acting on an object at rest?

• Yes, because forces can be balanced.

• No, because forces cannot act on a stationary object.

• Yes, but only if the object is in motion.

• No, because forces only act on moving objects.

• mass

• speed

• volume

• temperature
