1. Acceleration

2. A car traveling at 60 mph slams on the breaks to
avoid hitting a deer. The car comes to a safe stop
6 seconds after applying the breaks. What is the
car’s acceleration?
Velocity(final) - Velocity(original)
Acceleration =
time
0 mph - 60 mph =
6 seconds
- 60 mph =
6 seconds =
- 10 miles per hour per second

Objective
SWBAT define and calculate acceleration

5. Vocab
Acceleration - The acceleration of an object is a measure of how quickly its velocity changes.

6. Formulas Acceleration= final velocity- starting velocity time
Change in velocity = final – starting velocity velocity
Acceleration= change in velocity

7. Using a formula triangle
Boardworks GCSE Additional Science: Physics
Speed and Acceleration
Using a formula triangle
A formula triangle helps you to rearrange a formula. The formula triangle for acceleration (a), speed (s) and time (t) is shown below.
So to find acceleration (a), cover up a…  x
…which gives the formula…
a = s t
Cover the quantity that you are trying to work out.

8. - A constant acceleration produces a straight line or linear slope (rise/run) The slope of a non- linear velocity-time graph (rise/run) will predict an objects instantaneous acceleration. a = v/t

9. A car traveling at 60 mph accelerates to
90 mph in 3 seconds. What is the
car’s acceleration?
Velocity(final) - Velocity(original)
Acceleration =
time
90 mph - 60 mph =
3 seconds
30 mph =
3 seconds =
10 mph/second
