Acceleration • Acceleration is the rate of change of velocity. It is a vector quantity. =
Acceleration • The units used for acceleration are m/s2 • This actually means meters per second per second. • Let’s have a look a sample problem 1 on page 374.
Acceleration • On a velocity time graph, the slope of the line = the acceleration.
Acceleration • Negative acceleration is when the final velocity() is less than the initial velocity (). • We will try sample problem 2 on page 377.
Acceleration • Now try the CYU questions on page 379. • #2,4,5,6
Graphing Accelerated Motion • Constant acceleration shows a straight line on a velocity-time graph.
Graphing Accelerated Motion • The area under a velocity-time graph shows the displacement.
Graphing Accelerated Motion • Sample problems 1 and 2 on page 382 can help us practice this.
Graphing Accelerated Motion • CYU page 385 • #3,4,7
