A space shuttle is returning from a mission in space. It is currently burning fuel to help slow it down as it enters the atmosphere. Is the space shuttle in free fall? Why?
a. Yes, because it is not on the ground.
b. No, because the fuel provides another force besides gravity.
c. Yes, because it is falling down towards earth.
d. No, because air resistance is greater than the force of gravity.
B. No, because the fuel provides another force besides gravity
