At this moment, the mass of the entire Earth is pulling down on me, yet I can temporarily move my entire mass away from it by exerting less than 1 calorie of energy.
Another is that because of gravity, the universe and our reality are nothing like what they appear. For example, the Earth does not have a simple elliptical orbit around the Sun. If you could actually look at it, the Earth traces a wobbly orbit around the Sun. Why? Because the Earth is locked with our moon, which is relatively large. The Earth and moon actually orbit each other, with the center of mass being what orbits the Sun.

A beautiful, wonderful dance!
