- investigating motion
- 1.set up apparatus, mark a line on the ramp just before the first light gate
- this makes sure the trolley starts from the same point each time
- Practical
- 2. measure the distances between light gate 1 2 and 3
- 3. hold the trolley still at the start line and then let go, so it starts to roll down the slope
- 4. as it rolls down the ramp it will accelerate, when it reaches the runway at a constant speed
- 5. each light gate will record the time when the trolley passes through it
- 6. time it takes to travel between gates 1 n 2 can be sued to find average speed on the ramp
- 7. between agtes 2 and 3 gives the speed on the runway using the formula speed= distance/time
- the acceleration can be found by using acceleration= change in speed/time
