P H Y S I C S Chapter 1: One-Dimensional Motion Section 1B: Acceleration Objectives: 1)We will calculate the acceleration of an object 2)We will list the three ways an object can accelerate

Acceleration Equation Change in velocity over time a  acceleration (m/s 2 ) v  final velocity (m/s) v o  initial velocity (m/s) t  time (s)

Acceleration Three ways:  Increase speed  Decrease speed  Change direction

Acceleration Positive  getting faster  a = +10 m/s 2 Negative  getting slower  a = -10 m/s 2 Zero  no change (constant)  a = 0 m/s 2
