Torque Objectives: Describe the factors that determine whether two objects will balance each other Predict how changing the position of a mass on the balance will affect the motion of the balance Use a balance to the find the masses of unknown objects 1. Open the PhET Simulation Balancing Act - act/latest/balancing-act_en.html 2. Choose “Intro” tab. Play around with the simulation for a few minutes to understand/ explore the functionalities of the different components. 3. To check if the wooden board is balanced, remove supports under the board by toggling the switch at bottom of the screen to right. Case-1: Place 5 kg fire extinguisher at 2 m mark to the left of the pivot. Where should you place the 10 kg trash can to balance the board? Show your calculations. The trash can should be at the 1 m mark Case-2: Consider this situation without using the simulation: 1
