| Question | Answer |
| Definition of average velocity | v=Δd/Δt |
| Speed and angular velocity relationship | Ï=v/r |
| Definition of acceleration | a=Δv/Δt |
| Time of Free fall | t=√2y/g |
| Acceleration and angular acceleration realtionship | α=a/r |
| Weight | W=mg |
| Weight on an incline (parallel) | F=mg sinθ |
| Weight on an incline (perpendicular) | F=mg cosθ |
| Centripetal force | Fc=mv^2/r |
| Centripetal speed | v=2πr/T |
| Orbital Speed | v=√G(M/r) |
| Power | P=Fv |
| Work-energy theorem | W=ΔKE=½mvf^2-½mvi^2 |
| Conservation of energy | KEi+PEi=KEf+PEf |
| Conservation of energy (friction) | KEi+PEi=KEf+PEf+Energy (Ff*d = energy lost from friction) |
| Momentum and angular momentum | L=pr |
| Impulse (change in momentum) | Δp=FΔt=mΔv |
| Change in angular momentum | ΔL=τnetΔt=IΔω |
| Conservation of momentum (elastic) | m1v1i+m2v2i=m1v1f+m2v2f |
| Totally inelastic | m1v1i+m2v2i=(m1+m2)vf |
| Recoil | (m1+m2)vi=m1v1f+m2v2f OR m1v1f=-m2v2f (if v1=0 m/s) |
| Conservation of angular momentum | (I1)f(ω1)f+(I2)f(ω2)f=(I1)i(ω1)i+(I2)i(ω2)i |
