PPT-Linear Momentum

Linear Momentum Momentum is a measure of how hard it is to stop or turn a moving object p m v single particle P Σ p i system of particles Problem How fast must an electron move to have the same momentum as a proton moving at 300 ms. You should be able to solve 1D and 2D Momentum problems.. Linear Momentum. Antoine Lavoisier proved that mass was conserved by burning iron in a closed system. (The mass of any closed system remains constant.). Chapter 7. 7.1 The Impulse-Momentum Theorem. This section deals with time-varying forces affecting the motion of objects. .

Kinetic energy- energy of an object that it possesses due to its motion. . Common examples. A baseball thrown by a pitcher, although having a small mass, can have a large amount of kinetic energy due to its fast velocity.. What is Momentum? Unit 8 Section 3 Momentum Momentum is a property of ALL moving objects Momentum is the product of the mass and velocity of an object. Momentum = mass x velocity ( P=M x V) Momentum is labeled as kg x m/s with a direction.
