UNIFORMLY ACCELERATED MOTION

For constant straight line motion (s₀, s, v₀, v, a, t) :

if set t_i = 0: a = (v - v₀)/t and v = v₀ + at

mean speed: v_av = (v₀ + v)/2

Equations of Constant acceleration:

• v = v₀ + at
• s = s₀ + v_avt = s₀ + (v₀ + v)t/2 = s₀ + v₀t + at²/2
• v² = v₀² + 2as

For motion along general path with constant a_T :

• l₀ , l, v₀, v, a_T, t
• Same equations as before, but with l and a_T
• Use path length; recall that straight line equations use displacement
