1

What is acceleration defined as?

The rate of change of velocity (divided by time)

2

What is the difference between speed and velocity?

Velocity is like speed, but it must have a direction, eg. speed = 20mph , velocity = 20mph to the left

3

What is the equation that we can use to work out acceleration?

acceleration = change in velocity
------------------
time

4

What is the smaller equation for acceleration?

a = v - u
------
t

5

What is the unit for acceleration?

m/s/s = m/s2

6

What are negative accelerations?

Decelerations/slowing down/retardations

7

What is the equation that can be used to work out speed?

speed = distance
---------
time
