Question | Answer |
---|---|
Translational motion | x = x 0 + v 0 t + 1/2at2 Vƒ = Vo + at |
Frictional force | f max = μ Ν μk < μs always |
Uniform circular motion | Fc = mac = mv2 /r ac= v2 /r |
Momentum, Impulse | I = F Δt = ΔM M = mv |
Work, Power | W = F d cosθ P = ΔW/Δt |
Energy (conservation) | ET = Ek + Ep E = mc2 |
Spring Force, Work | F = -kx W = kx2 /2 |
Continuity (fluids) | A v = const. ρAv = const. |
Current and Resistance | I = Q/t R = ρl/A |
Resistors (series, par.) | Req = R1 + R2 . . . 1/ Req = 1/ R1 +1/ R2 |
Sound | dB = 10 log 10 (I/I0 ) beats = Δ f |
Thermodynamics | Q = mc Δ T (MCAT !) Q = mL |
Torque forces | L1 = F1× r1 (CCW + ve) L2 = F2 × r2 (CW -ve) |
