Contents
Outcomes
- Pupils can confidently rearrange the speed equation
- Pupils can apply the speed equation to various situations
- Pupils can convert between different units for speed
Specification References
1.3 recall and use the relationship between average speed, distance moved and time: average speed = distance moved / time taken
Starter
- Put a couple of speed conundrums on the board (when do two trains/cars pass)
Main Body of Lesson
- Rearrange the speed equation without going through the equation specifically, i.e. try to do it through words and the meaning of the quantities e.g. if I'm covering 5 m per/every second how far will I go in 10 seconds. Lead this into forming the equation. The final version (t = d/s) is trickier to visualise, try it with some simple numbers (e.g. moving at 20m/s over a course of 100m, how long will it take)
- Rearranging equations – go through a method for rearranging equations (such as diagonal movement for simple equations or standard maths cancellation)
- I have a worksheet somewhere for practicisicisng this. (AGR)
Plenary
- Practice questions on rearranging (add some tricky ones at the end e.g. KE or T pendulum for extension)
Homework
speed questions with some miles and kilometers in and rearrangements needed
