What did Galileo discover about moving bodies and force in his experiments with inclined planes?
Gravitational Torque Unlike tension force, which needs to be physically attached to something to act on it, gravity is a long distance force that acts on basically everything. This means that an object has gravity acting on every single particle in that object. Imagine a falling wrench. Each particle of that wrench is being pulled down the same amount by gravity. It's important to consider that one end of a wrench weighs more than the other. That means that it wouldn't simply fall without rotating, but would probably rotate in the direction of the heavier end. This effect is replicated by applying the force of gravity on the center of gravity. This is the equation for calculating it: x(cg) = (x(1)m(1) + x(2)m(2)) / (m(1) + m(2)) I won't go into why this is the equation, but I can discuss
