Question
What are control variables in an acceleration investigation, and why are they important?
Answer
Control variables are the factors that are kept constant throughout the investigation to ensure that the results are valid. They are important because they help to isolate the effect of the independent variable on the dependent variable, allowing for a clearer understanding of the relationship being studied.
Explanation
This question tests the understanding of the concept of control variables in scientific investigations. It assesses the student's ability to explain their significance in ensuring reliable and valid results.
Common mistake
Control Variables Confusion
Students often forget to identify all control variables in an acceleration investigation, focusing only on the changing variables.
To fix this, students should list all factors that must be kept constant, such as surface type, mass of the trolley, and angle of the ramp, to ensure a fair test.
