Quest:
... Work might also be done on an object to raise it to a higher height. In this case, the work done is the force opposing gravity times the distance it rises. We can get this energy back by releasing the object and allowing it to fall. Try it once right now. The amount of energy an object has because o ...

Gravity and Friction
... •If acceleration due to gravity is constant, and W = m x g, than the more massive an object is, the greater its weight (and the greater its gravitational force) • This is consistent with what we learned from F = m x a and our gravity definitions • As mass increases, so must W (the force) so that g s ...

... If a feather and a coin were dropped from the same height at exactly the same time, which would hit the ground first? Why? What about in the absence of air resistance? Why? What about skydivers … how do they control the speed of their descent? Newton’s First Law of Motion An object at rest will sta ...

Force and Motion
... An object is in EQULIBRIUM when the sum of all of the forces acting on it is zero. An object in EQUILIBRIUM will either be (and remain) at rest (no motion), or Will move with CONSTANT VELOCITY ...
