Note the ball oscillates between -1m and 1m. Play the simulation: 16. Which form of energy does the blue curve represent? 17. Which form of energy does the red curve represent? 18. Which form of energy does the green curve represent? 19. At which position(s) is the kinetic energy equal to zero? 20. At which position(s) is the potential energy equal zero? 21. At which position(s) the kinetic energy equal to the potential energy? 22. What is the numerical value of the total energy? (J) The time it takes for the ball to start and go back to its initial position is called the period of oscillation of the spring. 23. Estimate the period (5) Click reset and change the spring constant to 3.5 N/m 24. What is the value of the total energy? 25. How does the maximum value of the kinetic energy compare to the previous case? 26. Estimate the period (s) 27. For a fixed spring constant, explore how the period depends on different the masses.
