... There are times when you want to access the properties of each individual body when applying a custom global force. A good example of this is gravity at the Earth's surface. A general description of the force generated by the Earth's gravitational field near the Earth's surface is given by: F = mg ...

Moment of inertia
... Write an expression for the torque applied by each Counterclockwise torques are positive; clockwise torques are negative. If α = 0 (“static equilibrium”, “dynamic equilibrium”): This means that the net torque (about any pivot) is zero Choose a pivot on top of a force whose value you don’t know and d ...
