WebMomentum is "mass in motion", or a measure of how much motion an object has. Algebraically, momentum is defined as the product of an object's mass and velocity, . Momentum is a vector - the direction of the momentum matters. Any vector can be resolved into components. Generally, we resolve vectors into horizontal (x) and vertical (y) … WebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned.

WebFor a planet of mass m in an elliptical orbit, conservation of angular momentum implies that as the object moves closer to the sun it speeds up. That is, if r decreases then v must increase to maintain the same L. Thus near perihelion it speeds up and near aphelion it slows down. Both energy conservation and angular momentum conservation are ...

WebNewton's Cradle is a classic physics demonstration frequently seen as a desk decoration. This demonstration uses four or more suspended balls to demonstrate conservation of energy and conservation of momentum in a fairly elastic collision. While this demo is simple, it is easy to damage it by tangling the balls, so it must be packaged carefully. Web(c) Find: The angular velocity which provides the maximum power to the wheel. Solution: To find the maximum power, take the derivative of power with respect to angular velocity. The values of angular velocity at which this derivative is zero then represent conditions where the power is either a minimum or a maximum. There are two such roots, i.e.
