Lesson details
Key learning points
- A dynamics trolley speeds up (accelerates) along the whole length of a steep ramp.
- Instantaneous speed is the average speed over a very short time period.
- Instantaneous speed can be estimated by measuring movement in a small time period.
- Anomalous readings should be repeated and replaced or removed from sets of repeat readings.
Keywords
Dynamics trolley - A dynamics trolley is a wheeled object used in experiments. It moves very smoothly over flat surfaces.
Average speed - The average speed is the total distance travelled divided by the total time for a journey.
Instantaneous speed - The instantaneous speed of an object is the speed at a particular moment in time.
Anomalous reading - An anomalous reading is a result which is significantly outside the pattern in a set of results.
Common misconception
When the trolley is released it speeds up quickly at the start and then rolls at a constant speed.
Show a video of an accelerating trolley in slow motion identifying the distance travelled in successive equal intervals of time.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
