Question

AN astronaut on the Moon has a mass (including his spacesuit and equipment) of 180 kg. the acceleration due to gravity on the Moon is 1.6 m/s2 (seconds squared).
a) calculate his weight on the moon.

the astronaut climbs 100m to the top of the crater .

b) by how much does his gravitational potential energy (g.e.p) change?

c) Does his g.p.e increase or decrease?

Answer 1

weight=mass*acceleration
gpe=m*acceleration*height
If he goes to the top, his gpe increases.

Answer 2

9.8
