Answer 4

refer to paper.

Question 5

During this course, you have conducted an experiment to study the effect of speed on distance travelled. write an hypothesis

Answer 5

if the height is increases, then the speed of a trolley car increases

Question 6

List the equipment needed

Answer 6

1 x dynamic trolley
1 x stopwatch
1 x metre ruler
1 x phone
1 x ramp
1 x rubber band

Question 7

Write down a method

Answer 7

1. measure a fixed distance in the classroom for example 4 metres
2. place ramp at a certain angle and push dynamic trolley
3. using the stopwatch measure how long it took for the trolley to travel 4m or less
4. record results
5. repeat steps and switch to digital technology

Question 8

explain some limitations and advantages of using digital and analogue technology

Answer 8

limitations:
- difficulty in calibration
- induce errors

advantages:
- measurements are recorded
- responds faster to change
