What is the force that opposes forward motion of an object?

Back

Drag is the force that opposes the forward motion of an object.

Front

What are forces that are not equal in strength and are opposite in direction?

Back

Unbalanced forces cause a change in the object’s motion.

Front

What is the attractive force between objects that moves objects downhill?

Back

Gravity is the attractive force that pulls objects towards each other, moving them downhill.
