We tested the effects of friction on a toy car. We made a ramp for the car, and we timed the car on different surfaces. We used materials such as wood, felt, foil, plastic, and construction paper. We found that rough surfaces create more friction for the car, and smooth surfaces create less friction for the car. Some of the surfaces even caused the car to stop completely. Watch our video to see our experiment!

4. Describe effects of friction on moving objects.
  • Identifying momentum and inertia as properties of moving objects
  • Identifying ways to increase or decrease friction

    1. Plan and carry out an experiment to determine the effects of balanced and unbalanced forces on the motion of an object using one variable at a time, including number, size, direction, speed, position, friction, or air resistance (e.g., balanced forces pushing from both sides on an object, such as a box, producing no motion; unbalanced force on one side of an object, such as a ball, producing motion), and communicate these findings graphically.
