Question

Dora 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 2 4 6 Trial 2 2 4 2 6 Which is the constant variable in this experiment?

Answer 1

The potential energy

Step-by-step explanation:

Answer 2

The constant variable in Dora's marble down a ramp experiment is the total energy of the marble. When the marble is at the highest point, it's potentinal energy is the most significant, as the marble rolls down, it increases it's kinetic energy and decreases it's potential energy at the same rate, maintaining the same total energy all across the path.
