The Looped Energy Track enables your students to investigate energy conversions - potential kinetic and rotational. The Energy Track apparatus consists of two silver boards attached to a stand. Between the two plastic tracks is a scale displaying the vertical height above the track on the base. The maximum vertical height above the base is 34cm.Many investigations are possible and these are listed in the documentation supplied with the unit.To calculate the speed of the ball bearing at the bottom of the ramp a timer with a resolution of 0.1 ms or better should be used. Our Time Speed & Acceleration (TSA) unit is ideal for this task (available separately).It is also possible to measure the speed of the ball bearing at the bottom and top of the loop.The TSA Timer and Light Gates are not included.
