Acceleration is the rate of change of an object's velocity, whether it's speeding up or slowing down. Learn how to analyze velocity-time graphs and calculate acceleration in this informative presentation.

Acceleration Speeding Up and Slowing Down
Acceleration • The rate at which an object changes its velocity • Describes how the velocity of an object changes • Acceleration can be a: • Change in speed OR • Change in direction • Acceleration can mean speeding up or slowing down • Symbol = • m/s2 Slide 1
Analyzing Velocity Time Graphs • We can use velocity time graphs to calculate acceleration and determine if acceleration is positive or negative Slide 2
Formula = acceleration = change in velocity = time Slide 3
