Momentum Principle
- Equations to remember
- Conservation of momentum: m1v1 = m2v2
- Iterative change in Momentum
- Update the force
- Find the new Fnet
- Update the Momentum
- pf = pi + Fnet*Δt
- In PHYS 172, we typically use
pf/m for vavg, for other classes
you will want to add the pf and pi
and divide by mass.
- Update the position
- rf = ri + pf/m * Δt
