The steeper the line on
a distance-time graph
of a moving object, the
greater its speed is.
Object Speeding

Object Slowing Down
(Decelerating)

### Slide 3

Speed vs. Velocity
Speed
· Speed measures how fast you're going.
· It is measured in m/s.
Velocity
· Velocity measures speed in a given
direction.
· It is measured in m/s².…read more

### Slide 4

Useful Equations
Speed = Distance ÷ Time
D
S=D÷T
m/s = metres ÷ seconds SxT
e.g. Mary ran 200m in 40 seconds. What is
her speed?
200 ÷ 40 = 5m/s…read more

### Slide 5

Useful Equations
Acceleration is how quickly the velocity
is changing. Change
in
Acceleration = Change in Velocity ÷ Velocity
Time Taken
m/s² = m/s ÷ seconds Acceleration x Time Taken
e.g. A skulking cat accelerates steadily from 2 m/s to 6
m/s in 5.6 s.
What is its acceleration?
6­2=4
4 ÷ 5.6 = 0.71m/s…read more
