Jack rolled a marble down a ramp and recorded the potential energy and kinetic energy of the marble at different positions on the ramp, as shown in the table below. Marble experiment Height of Marble from Ground (meters) Potential Energy of Marble (Joules) Kinetic Energy of Marble (Joules) Total Energy of Marble (Joules) Trial 1 1 1 3 4 Trial 2 2 3 1 4 Which of these is the test variable (independent variable) in this experiment? Mass of marble Kinetic energy of marble Potential energy of marble Height of marble from ground

An independent variable is the variable in an experiment that you change to see if it has an effect on the dependent variable. In this case, Jack wanted to see whether the position of the marble on the ramp (which would be the height) has an effect on the kinetic and potential energy of the marble, then the height would be the independent because it is what is being changed.

Added note:

The dependent would be the kinetic and potential energy and the constant would be the type of marble.

Answer:

The answer would be the height of marble from the ground

Explanation:

you change the height of the marble from the ground (you test the heights)
