Science Inquiry. Lab Station 1 Period 6. Problem/ question:. Will the texture of a surface change the amount of friction?. Independent Variable:. Our independent variable is the texture of the surface. Dependent Variable:.
Lab Station 1
We know that when the marble starts at the top of the ramp it has the most potential energy, when it roles down the ramp the potential energy turns into kinetic energy. Potential energy is based on position. Kinetic energy is based on speed. Friction causes objects to stop. Friction is based on kinetic energy which makes objects move,then friction makes the object stop.
