Question 2 • Physics

Which is the best prediction Shari could make?

Answer
A
Her weight is lower on Venus because the acceleration due to gravity is lower.
B
Her weight is greater on Venus because Venus has less mass.
C
Her weight is lower on Earth because it is farther from the Sun.
D
Her weight is greater on Venus because Venus has a smaller diameter.

Explanation

Weight depends on the strength of gravity at a planet’s surface. Venus has a lower surface gravitational acceleration than Earth, so Shari would weigh less on Venus. Venus’s smaller diameter alone does not mean her weight is greater; surface gravity depends on both a planet’s mass and its radius.
