Dec 21, 2017 · 2 So I am doing an experiment with gravity car, basically dropping a hanging mass and spins the axle using a pulley system. And then I thought although the work formula W=Fd …
What is the relationship between gravity and inertia?
Gravity - Same dip (curve) due to mass (energy) of the body manifests as gravity for other bodies. So, their origin is same and that is curving of space. Inertia is nothing but gravity of the body …
