We just learned about this! Gravity is a force of attraction. Every object in God's creation is attracted to one another. Right now, there is gravity between me and this computer. There is gravity between the earth and the sun, which causes us to orbit. The amount of gravity depends on the mass (how heavy something is) and the distance between the two objects. Gravity, is a force, it is not something we can see. A force is a push or pull. We can't see what a push or pull looks like, right? Hopefully this makes sense!
