rocedure Start Virtual Physical Science and select Potential Energy to Kinetic Energy from the list of assignments. The lab will open in the Mechanics laboratory. The laboratory will be setup with a block on a ramp and with gravity pulling vertically down. The surface is frictionless. You will release the block from different heights and watch it slide down the ramp. You will measure the speed of the block at the base of the ramp and use that to calculate the kinetic energy. You will be measuring the height of the block and the speed of the block when it hits the bottom. In the following table record the y height of the block, found in the left-hand side of the data table at the bottom of the screen next to y. Click the red Start button to release the block. It will slide to the bottom of the ramp and explode when it hits the bottom. Record the total velocity vtot in the data table. Now repeat the experiment four more times, starting the block in a different place every time. Click the blue Reset button to return the block to the top of the ramp. Click on the
