A box slides across a floor at a constant velocity. What forces act on the box?

• friction, gravity

• friction, tension, gravity

• friction, normal force, gravity

• friction, normal force, net force

Match description with free-body diagram.

• A book is at rest on a tabletop.
• A gymnast holding onto a bar, is suspended motionless in mid-air. The bar is supported by two ropes that attach to the ceiling. Diagram the forces acting on the combination of gymnast and bar.
• An egg is free-falling from a nest in a tree. Neglect air resistance.
• A flying squirrel is gliding (no wing flaps) from a tree to the ground at constant velocity. Consider air resistance.
