In this simulator, you will be given a scale model of an inclined plane with a mobile and a counterweight. You will also have a protractor with which to measure the angle of inclination and a balance on which to weigh the masses to be added to the mobile and the counterweight in order to reach a specific acceleration. You will need to draw a free body diagram in order to analyze the forces applied to the mobile and the counterweight so that the mobile moves at a certain amount of acceleration.
