Calculating speed
I can calculate speed.
Lesson details
Key learning points
- The greater the speed of an object, the shorter the time it takes to cover a certain distance.
- The greater the speed of an object, the more distance it travels in a certain time.
- Speed = distance / time.
- Speed is measured in m/s or km/h or miles/h.
- m/s is the number of metres travelled each second.
Common misconception
"Constant speed" can be interpreted as "moving all the time", and "steady speed" as "not too fast".
Use the terms with care, qualifying them with examples when they are used, e.g. "a constant speed of 4 m/s" or "a steady speed of 100 m/s".
