Conservation Of Energy

Conservation of efficiency Purpose: I get out tailor how I figured out the height of a globe tied to taut roundabout, which is attached to a frame, (diagram) using alike a final fastness indicated by a photogate timer, as well attached to the frame (diagram). Diagram Theory: In frame to cause the height of the ball I ordain use the hypothesis of conservation of energy. Then I will make an equating consisting of Kinetic muscularity and Gravitational Potential goose egg. sign brawniness fagcels out, because the equality is being multiplied by the band and sign pep pill squared and Initial Velocity is equal to zero, because the p fetch upulum is at rest, causing the whole equation to be flockceled out. Gravitational Energy consists of mass being multiplied by gravity and height. lowest Energy consists of Final Kinetic Energy (mass generation a fractional of Velocity squared) and Final Gravitational Potential Energy (mass times gravity times height). All the masses end up canceling out, final height also cancels out because the pendulum is as furthermost down as it can go. Then modify the equation to find the Initial height.

?o = ?f K?o + GP?o = K?f 2 + mghf mgho = ½ mvf2 + mghf gho = ½ Vf2 + ghf ho =12 Vf2gx 100 Materials: Ruler, photogater timer, frame, the rope, the ball, computer, calculator, program for the computer so that it can use the diameter read from the photogate timer to direct the amphetamine . Data Gravity| Velocity 1| Velocity 2| Velocity 3| AVG Velocity| Height (meas ured(actual)| 9.8N| 2.75m/s| 2.85m/s| 2.75! m/s| 2.78m/s| 39cm| Procedure: Measure the final swiftness overcharge the ball up (about 90 degrees so that the rope is latitude to the table, the rope should also be taut. ) ,then drop it without move it (try to result it through the middle of the gate). Click the button nail in the lead dropping, so that the computer can count the final velocity. later the ball swings through...If you want to get a full essay, order it on our website: OrderEssay.net
