• Speeding Up Index o Something per something else = index o something/something else = speed/time = acceleration • To find acceleration… (two ways) 1. Data Table Way Example: t v Δt (t 2t 1) Δv (v 2v )1 a (Δv/Δt) 0s 5mph -- -- -- 2s 25mph 2 20 10 4s 45mph 2 20 10 2. Acceleration Equation: (a) = Δv/Δt (0s, 5mph) (4s, 45mph) a = Δv/Δt = (45mph-5mph)/(4s-0s) = 40mph/4s = 10mph/s v = v 0+ at v 0= v – at a = v – v /0 t = v – v /0 Example #1: If at 0 seconds, a truck is moving at 10mph and is at 30mph 10 seconds later, what is the acceleration of the car? a = v 1– v /0 v 0= 10mph v 1= 30mph a = 30mph – 10mph/10s-0s t0 = 0s t1 = 10s a = 20mph/10s a = 2mph/s Example #2: A car starts at 5mph and accelerates at a rate of 3mph/s. How long does it take to get at 30mph? t = v – v 0a à t = (30mph - 5mph)/(3mph/s) = 25/3 = 8.33 seconds • “Falling” o velocity: speed is increasing; direction o acceleration: constant o position: downward; if up positive, decreasing if up negative, increasing Graph A: Graph B: Graph C: Graph D: ACCELERATION positive negative Graph C Graph A t Speeding Up Slowing Down p E Graph B Graph D V n Slowing Down Speeding Up • Velocity is… o Speed (value) o Direction ( + or – ) a = Δv/Δt = v –2v /t 1– 2 1 absolute speed = velocity value bars! • Displacement o Area between V. curve and t axis o Displacement (Δx) = (v)(Δt) area (square) = base(b)height(h) area = 1/2bh (triangle) area (trapezoid) = 1/2bh (b +1b ) 2 Example: What is the displacement over 3 seconds? Δx = (v)(Δt) 10m/s =(10m/s)(3s) =30m or A = bh = (3s)(10m/s) = 30m 1 2 3
