 torque T=FD┴ torque is force times moment arm both the magnitude of the force and the length of the moment arm equally effect the outcome of torque momentum M=mv quantity of motion linear velocity v=rw angular velocity ω=v/r ω=θ2-θ1/Δt who wins collision equation (momentum of both objects is given.. which direction wins?) v=(m1v1+m2v2)/m1+m2 or think of it as v=(M1+M2)/m1+m2 what do you to for degrees to radians divide what do you do from radians to degrees multiply work W=Fd creating force over distance power P=W/Δt or P=Fd/Δt work over time kg to newton conversion 1kg=9.8N Impulse Ft=ΔM or Ft=mv2-mv1 change in momentum angular momentum H=Iω quantity of angular motion Inertia I=mr2 or I=Σmr2 sometimes r is replaced with k  resistance to motion Φ angular distance θ angular displacement α (alpha-fishy) angular acceleration ω angular velocity σ angular speed t time T torque v linear velocity d distance/displacement RF reactive force R resistance F force Fm Force of maximum static friction Fk Force of kinetic friction μs static friction μk kinetic friction amount of force for maximal static friction Fm=μsR amount of force for kinetic friction Fk=μkR force F=ma angular acceleration α=ω2-ω1/Δt or α=Δω/Δt angular impulse Tt=Iw2-Iw1 or Tt=ΔH change in angular momentum I inertia H angular momentum Authormiss_bayley ID325792 Card Setbiomech exam 2 equations Descriptionono Updated2016-11-21T11:01:19Z Show Answers
