1. What force holds the planets in motion around the sun?
force
A. air resistance
C. gravitational
B. electrical
D. magnetic
2. As the skydiver is falling. a force is pulling the skydiver and his or her parachute
toward the earth. This force can make the parachute fall very fast. However, the
parachute slows the skydiver down because another force pushes the parachute
back up and creates a force opposite to the force that causes it to fall. What is
this upward force acting on the parachute?
A. force of friction
B. force of gravity
C. air resistance
