Yoyos 0 Overview Using this Resource Connecting to the Curriculum Marking Student Responses Further Resources This task is about different types of energy. A yoyo was dropped until its string was extended fully. Question 1Change answer a) Name one form of energy that the potential energy of the yoyo would have been transformed into during the drop. a) Name one form of energy that the potential energy of the yoyo would have been transformed into during the drop. Question 1Change answer b) The yoyo reaches the bottom of its path and starts its way back up again, but does not reach the top. Why does it not return to its starting point? b) The yoyo reaches the bottom of its path and starts its way back up again, but does not reach the top. Why does it not return to its starting point? Question 1Change answer c) Yoyo players can make the yoyo go down and spin right back up again. What form of energy is used by the yoyo players to get the yoyo back up to where it started from? c) Yoyo players can make the yoyo go down and spin right back up again. What form of energy is used by the yoyo players to get the yoyo back up to where it started from?
