Monday, Oct. 22nd (p. 15)Objective: Students will be able to understand how to calculate acceleration using a step by step method.

Bell Ringer:1. Your car is initially going 30

m/s and you come to a stop in 3 seconds. What is your acceleration?

a = (vf – vi)/Δt = (0 – 30 m/s)/3 sa = -10 m/s2

2. What are the units of acceleration and what do they mean?
