12.3 Investigation: Using the Inclined Plane to Do Work PURPOSE To study the characteristics of the inclined plane HYPOTHESIS I believe that as the angle of the inclined plane decreases towards zero, the work required to lift the object up the board will become easier. APPARATUS  inclined plane  ring stand, support rod, and clamp  1.0 kg mass  Newton spring scale  metre stick PROCEDURE 1. Lay the inclined plane flat on the table. Attach the Newton spring scale to …showed first 75 words of 310 total…

(Assume the force of friction on the incline is about 0.75 times the force of friction on the level.) Record the work done in your observations. 9. Calculate the work done to lift the mass vertically to the point x. Record this figure in your observations. 10. Repeat steps 2 through 9 two more times. Use a different angle of the inclined plane each time. OBSERVATIONS
