PPT-MOMENTUM AND COLLISIONS LINEAR MOMENTUM

Momentum Mass x Velocity p mv The SI unit for momentum is kgm s Momentum and velocity are in the same direction Is a vector Using the equation p mv At the same velocity as mass increases momentum increases. e Ax where is vector is a linear function of ie By where is then is a linear function of and By BA so matrix multiplication corresponds to composition of linear functions ie linear functions of linear functions of some variables Linear Equations We will now quantify exactly how it hits the fan.. Momentum. Momentum = product of mass X velocity. Symbol for momentum is “p” (don’t ask me why). So, p = . mv. Momentum is also a vector and points in the direction of velocity. 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 m/s?. in kinetic plasma physics. Gérard. BELMONT. Laboratoire. de Physique des Plasmas. Ecole. .

The cost of “Property Damage Crash” (a typical backing up accident) is presently estimated at an average of $7,400 per event. & Energy in Collisions.

Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. AP Physics 1. M. Dimler. What to Expect from this Unit. Momentum. Impulse. Impulse-Momentum Theorem. Conservation of Momentum.

It’s the opposite of the impulse momentum relationship!. Ft = Δmv. Example. Consider a gun being fired.. A gun recoils when it is fired. . Momentum and Impulse. Objectives:. 1. Compare the momentum of different moving objects.. 2. Compare the momentum of the same object moving with different velocities.. 3. Identify some examples of change in the momentum of an object..
