EXPERIMENTAL INVESTIGATION 1.1 How does the height of a ramp affect the distance a toy car travels?
Equipment Ramp Metre stick
Method
1. Draw a start line on the ramp from which the toy car will be launched each time.
2. Using the metre stick, measure the height of block 1. Record the height in the results table.
3. Place the ramp on block 1. 4. Place the toy car on the ramp at the start line. 5. Allow the toy car to travel down the ramp. 6. Measure the distance the toy car travelled from the end of the ramp. Record in the results table. 7. Repeat steps 4–6 two more times and record the average. 8. Repeat steps 2–7, adding another block each time.
