Question 2 of 20
Planets A and B have the same size, mass, and direction of travel, but planet
A is traveling through space at half the speed of planet B. Which statement
correctly explains the weight you would experience on each planet?
A. You would weigh less on planet B because it is traveling twice as
fast as planet A.
B. You would weigh the same on both planets because their masses
and the distance to their centers of gravity are the same.
C. You would weigh the same on both planets because your mass
would adjust depending on the planet's speed.
D. You would weigh more on planet B because it is traveling twice as
fast as planet A.
