Grandfather clocks are designed in a way that the weight at the bottom of the pendulum can be moved up or down by turning a small screw. Suppose you have a grandfather clock at home that runs slow
Should you turn the adjusting screw so as to raise the weight or lower the weight? A) Raise it. B) Lower it. C) It doesn't matter if you raise or lower the weight as long as you displace it by the right amount. D) It doesn't matter if you raise or lower the weight, as long as you displace it with the correct initial velocity. E) Raising or lowering the weight doesn't help. The screw is there so that you can add or take away weight.
