Alta High Physics Momentum Defined Linear Momentum is the product of mass and velocity Mathematically this becomes: ρ = mv Ρ (rho) – linear momentum m = mass in kilograms v = velocity in meters/seconds Hence change in momentum is Δρ = mΔV = mV f – mV 0
Alta High Physics Momentum and Force The rate of change of momentum of a body is equal to the net force applied to it. Mathematically this is represented by: ∑F = Δρ/t This can be derived by expanding equations we already know: F = ma = m{(V f – V 0 )/t} = (mV f – mV 0 )/t = Δρ/t Hence the second equation for change in momentum is: Δρ = Ft Another name for change in momentum is Impulse.

Alta High Physics Collisions and Conservation of Momentum In an isolated system momentum must be conserved. Momentum is most often used for Collisions Two type of Collisions Elastic Two objects collide and there are two objects move away In a perfectly elastic collision kinetic energy is conserved.
