gravity
Is gravity the same on all planets?
Gravity is what holds our world together. However, gravity isn't the same everywhere on Earth. Gravity is slightly stronger over places with more mass underground than over places with less mass. NASA uses two spacecraft to measure these variations in Earth's gravity.
How is gravity related to mass?
Gravity is the attractive pull between two objects that have mass. The strength of gravity is directly proportional to the amount of mass of each object.
Which planet would you weigh the most on? The least?
Since Pluto was demoted to a dwarf planet, Mars became the planet where you would weigh the least. Jupiter is the largest planet in our Solar System with the most mass.
How would your life be different if you lived on a planet with higher gravity? With lower gravity?
These faraway planets might remind you of home they're rocky, smaller than gas It's possible that Earth and the other inner planets of our solar system It would take more energy to resist gravitational pull, so the structures we have.
