2. How is average speed calculated?
3. Match the symbol to the quantity.
4. Why is the instantaneous speed of a trolley greater at the bottom of the ramp than near the top?
5. During an experiment, a trolley rolls down a ramp, getting faster as it moves. Which two statements are correct?
6. Calculate the speed of a trolley if it travels a distance of 10 cm in 0.2 s. Give your answer in m/s.
7. Match the key word or phrase to the explanation.
8. How can you check that a practical result is reproducible?
9. Which of these should be included in a good written method?
10. A pupil produces a graph to see if there is a relationship between two variables.What features would the graph have if the variables are directly proportional to each other?
11. A pupil produces a graph to see if there is a relationship between two variables. The points do not seem to follow a straight line.How should they draw a line of best fit?
12. A pupil suggests measuring the time it takes a trolley to roll 5 cm down a ramp using a stopwatch to get an accurate value of instantaneous speed. Why is this unlikely to produce an accurate result?
