Q.

A person can jump higher on the moon's surface than on the earth because –

A. the moon's surface is rough
B. the acceleration due to gravity in moon is smaller than that on the earth.
C. the moon is cooler than earth
D. the moon has no atmosphere
Answer» B. the acceleration due to gravity in moon is smaller than that on the earth.
Explanation: The acceleration due to the gravitational field of moon (g' = 1.62631 ms-2) is one-sixth of the acceleration due to gravity on the Earth. So the weight of the same body is also 1/6th on moon in comparison to that on the surface of the earth. It is due to this reason; a man can jump six times higher on moon than on earth.
