Gravity

Is gravity the same on all planets? 

Gravity is what holds our world together, But it isn't the same everywhere on earth. Gravity can be slightly stronger over places with more mass underground then places with less mass.

How is gravity related to mass?

Gravity is the attractive pull between to objects that have mass. The strength of gravity depends on how much mass is in that object.

Calculate your weight on the other planets in our system (If you're not sure what your mass is, use a 30kg Labrador retriever).

If you are 30kgs your weight will be 4.98kgs on the moon but on the sun you will weigh 812.16kgs, This will not change your weight but it will just make you feel that you weigh this much because of the gravity and your mass.

How would your life be different if you lived on a planet with higher gravity? With lower gravity?

If we were to live on a planet with lower gravity the air would change as well, The air would decrease compared to the air we are breathing now and it would make it hard to breathe. Yes we may be able to live in a place that has higher gravity, As long as it is not too different from what we have here on earth. Although we may have increasing join problems and would probably face fatal injuries from falling. We may only be able to adapt to this if you develop muscles.
