| Question | Answer |
|---|---|
| Δx (displacement) | Δx = xf - xi |
| s (speed) | s = d / Δt |
| v (velocity) | v = Δx / Δt |
| a (acceleration) | a = Δv / Δt |
| m (slope) | m = Δy / Δx (rise/run) |
| Fg (acceleration due to gravity) | Fg = mg |
| Fnet | Fnet = ∑Fn or Fnet = ma |
| Ff | Ff = μFn |
| Fg (universal gravitation) | Fg = Gm1m2 / d² |
| W | W = ΔKE or W = Fd |
| P (power) | P = W / Δt or P = IV |
| ME | ME = KE + PE |
| PE | PE = mgh |
| KE | KE = ½mv² |
| p (momentum) | p = mv |
| f (frequency) | f = 1 / T = #osc / Δt |
| v (wave speed) | v = λf = λ / T |
| Fe | Fe = kq1q2 / d² |
| V | V = IR |
