Mass on Table Applet In this simulation the masses will move if the tension in the string is greater than the frictional force on the mass on the table. Fill in the masses (5 to 20kg for the large mass, 5 to 10kg for the small mass, no decimals) and the coefficient of friction. Press Apply. Note the tension in the string and the friction. Press "Release Mass". Observe the drop in the tension if the masses move. The drop is due to the fact that as the mass on the table begins to move it no longer exerts the same force on the string. The hanging mass is still pulled by the same force of gravity as before but the mass on the table is not able to hold the same tension in the string. Calculate the acceleration of the system yourself. To check your answer click on the Answer button. Note: The movement of the system of masses has been slowed down in this simulation. The actual movement is too quick to see properly. |
