WHAT IS SPEED?
Speed is a measure of how fast an object moves. In other words, how far of a distance an object moves in a certain amount of time. 

Speed is measured in: 
meters per second (m/s)
Kilometers per hour (km/h)

p. 104-105

Slide 14 - Slide

Average speed

As an object moves its speed is constantly changing, though this is very difficult to measure.  Therefore we calculate the average speed, which is the speed over a certain amount of time.
Here a car is constantly changing 
its speed, but we only calculate the 
average speed throughout the journey.








p. 104-105

Slide 15 - Slide

Calculating speed


To calculate speed 2 things are needed:
The distance in meters (or kilometers)
The time in seconds (or hours)












The formula for calculating speed is:



The unit for speed is m/s (or km/h)
