An astronaut standing on the surface of the moon throws a ball upwards. The ball would: |
directly fall down from the point it was released hang in space go up and then come back to the surface of the moon keep going up never to come back |
go up and then come back to the surface of the moon |
The acceleration due to gravity on the surface of the Moon is 1.62519(412) m/s2 , about 16.6% of that on Earth's surface. Over the entire surface, the variation in gravitational acceleration is about 0.0253 m/s2 (1.6% of the acceleration due to gravity). Because weight is directly dependent upon gravitational acceleration, things on the Moon will weigh only 16.6% of what they weigh on the Earth. Hence, the ball will go up and then come back to the surface of the moon. |
