Which of these factors are experienced by a space shuttle in orbit? Check all that apply.

A. gravity

B. air resistance

C. friction

D. inertia

E. centripetal force

Gravity, inertia, centripetal force

Explanation:

Gravity: A space shuttle in orbit experiences gravity not just from the planet it is orbiting but from other celestial bodies too

Air resistance: There is no atmosphere in space so the shuttle experiences no air resistance

Friction: There is no atmosphere or surface that it is moving on so the shuttle experiences no friction

Inertia: Any body that is moving or stationary experiences inertia, the resistance to change in velocity whether it is moving or stationary

Centripetal force: The shuttle is in orbit, what keeps it in orbit is the centripetal force towards the center of the body it is orbiting

A. gravity (of any planet/star/celestial body around)

D. Inertia

E. Centripetal force
