... Sir Isaac Newton hypothesized that the force that pulls objects to the ground—gravity—also pulls the Moon in its orbit around Earth. An orbit is the elliptical path one body, such as the Moon, follows around another body, such as Earth, due to the influence of gravity. The centripetal force keeping ...

7-2 Conservation of Momentum
... Conservation of Momentum applies only in the absence of external forces! In the first two sample problems, we dealt with a frictionless surface. We couldn’t simply conserve momentum if friction had been present because, as the proof on the last slide shows, there would be another force (friction) i ...

Momentum
... • Momentum can change. Most often, the mass of an object remains the same, while the velocity changes. • Dp = mDv • Dv acceleration a = Dv/t Dv=at • Dp = mDv becomes Dp = m x a x t • Dp = Force x time = Ft F • This is called Impulse – I = Ft ...
