Acceleration • Change in velocity per unit of time. 𝑎= 𝑣−𝑣0 𝑡   Where: a = acceleration (m/) v = final velocity (m/ s) = initial velocity (m/ s) t = time (s)   Uniform Acceleration • Simplest kind of motion in a straight line which the speed changes at a constant rate. 𝑥−𝑥0= (𝑣+𝑣0)𝑡 2   𝑣=𝑣𝑜+𝑎𝑡  𝑥 – 𝑥 0=𝑣𝑜𝑡+ 1 2 𝑎𝑡2   𝑥 – 𝑥 0=𝑣𝑜𝑡− 1 2 𝑎𝑡2   2𝑎 (𝑥 – 𝑥 0 )=𝑣 2−𝑣 02  Where: x = displacement (m) = initial velocity = final velocity (m/s) t = time (s) a = acceleration (m/) •   Formula: •   Where: y = final height (m) = initial height (m) = initial velocity (m/s) = final velocity (m/s) t = time (s) g = acceleration due to gravity (9.8 m/s2) •   2 – DK I N E M A T I C S Module 2 Lesson 3 Elementary Physics I Formula: a @ + UV Me y Oy X —X9 = Voxt; VY— Vo nn Vy = Voxi Vy = Voy — gt st = y) X — Xo = Voxl; Y— Yo = AT dy = 0;2g(y — Yo) = VE — Voy Where: x = final displacement (m) = initial displacement (m) = initial velocity (m/s) t = time (s) y = final height = initial height = final velocity (m/s) g = acceleration due to gravity (9.8 m/) a = acceleration (m/) •
