How does gravity and inertia affect the earth?
The sun’s gravity holds the earth and the other planets within their orbits. Gravity on the earth keeps things from falling away into space, like us, rocks, sand, dirt, or anything else that is loose. Inertia and gravity interact to maintain the tight balance of us flying off into space and not falling into the sun. The combination of the two laws of physics is what keeps us where we are. Inertia and gravity also interact to keep the moon in it’s orbit.
