Classic Circular Force Lab
This lab will let you determine the speed needed to keep an object in circular motion. You will be able to change the force holding the object in a circle by clicking on the washers (each washer is 10 grams). You can adjust the radius of the circle by clicking on the masking tape that is just below the tube. You can also change the mass of the moving object using the arrows.
Find the velocity of the object by timing at least 10 revolutions. When you are ready to start the experiment, click on the begin button.
