After bringing a scale to the moon, the astronaut discovers they have a lower weight than they do on Earth. Why is this the case?
Because gravity is higher on the moon
Because the moon is larger than the Earth
Because gravity is lower on the moon
The scale is broken; your weight is the same everywhere
- 6. Multiple Choice

Newton's Second Law States:
For every action, there is an equal and opposite reation.
An object at rest remains at rest, unless acted upon by a net force. An object in motion remains in motion, unless acted upon by a net force.
- 10. Multiple Choice
Newton's Third Law States:
For every action, there is an equal and opposite reation.
An object at rest remains at rest, unless acted upon by a net force. An object in motion remains in motion, unless acted upon by a net force.
