Acceleration

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.

The Acceleration Formula  The formula for acceleration is show below: a = Δv Δt Δt  In this formula… “a” is for acceleration.“a” is for acceleration. “Δv” is change in speed. (Δv = v 2 – v 1 ) “Δv” is change in speed. (Δv = v 2 – v 1 ) “Δt” is for change in time. (Δt = t 2 – t 1 )“Δt” is for change in time. (Δt = t 2 – t 1 )  There is also a formula triangle for acceleration – use the Δv Δv a Δt

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.

Just a Reminder!!!  To solve problems you have to show me… 1. The proper formula. 2. Substitution of values with proper units. 3. The correct answer with proper units.
