go to that website And it will show you how old would you be on other planets http://www.exploratorium.edu/ronh/weight/
No, I would not.
No I have not landed on mars but I would like to go.
Down. The weight of th boy would be more then the weight on the otherside, since the girl got off, this weight is non-existant.
Yes. Depnding on the size, it would either go up or down. the Mass says the same.
If the rocket from earth looped into the Mars gravitational pull it should be pulled into a orbital path around the planet. But as on earth it would eventually slow down and be attracted to the surface of Mars were it would crash
it means there is more weight when you push down for example when you go swimming and when you go deeper the weight is pushing down on you
a space suit
Depends entirely on how fast you want to go, the weight of the space craft, how much cargo or provisions you need to take and how long you intend to take.
Where ever you go you would still be 15
If you roll it on its side down a slight slope, the full can would go faster because it has more weight.
You would need a rocket ship in order to travel to Mars. You would also need a space suit and an oxygen tank.
