Worked Solution
Step 1: Identify the aim (How surface texture affects distance).
Step 2: Surface texture is the independent variable.
Step 3: Distance travelled is the dependent variable.
Step 4: The angle of the ramp must be kept the same to ensure the block starts with the same amount of gravitational potential energy for a fair test.
Correct answer: The angle of the ramp.
