  1. Acceleration

  2. What is acceleration? • Acceleration is not rocket science! • Acceleration may seem tough but it is a lot like speed in terms of the calculations. • Acceleration is the rate of change in the speed of an object over time.

  3. The Acceleration Formula • The formula for acceleration is show below: a = Δv Δt • In this formula… • “a” is for acceleration. • “Δv” is change in speed. (Δv = v2 – v1) • “Δt” is for change in time. (Δt = t2 – t1) • There is also a formula triangle for acceleration – use the Δv a Δt

  4. Types of Acceleration • Average acceleration – The total change in speed divided by the total time elapsed. • Constant acceleration – The same change in speed occurs for each successive unit of time. Positive & Negative Acceleration • Positive acceleration is another way of saying you’re speeding up. • Negative acceleration (aka deceleration) is known as slowing down.

  5. Just a Reminder!!! • To solve problems you have to show me… • The proper formula. • Substitution of values with proper units. • The correct answer with proper units.

  6. Practice Problems • Page 385 Sample Problem #1. • Page 386 Sample Problems #2 & #3. • Page 387 Sample Problems #4 & #5. • Page 388 Sample Problem #6. Class Work/Homework • Page 388 #’s 1-5 & 7-14.

  7. THE END!!!
