New cards

Motion in one direction formulas

v_f = v₀ + at

Δx = v₀t + ½at²

v_f² = v₀² + 2aΔx

New cards

avg velocity formula

v̄ = Δx/Δt = (x_f - x_i) / (t_f - t_i)

6

New cards

avg speed formula

path length (m) / elapsed time (s)

7

New cards

avg acceleration formula

ā = Δv/Δt = (v_f - v_i) / (t_f - t_i)
