Energy Essays - Physics, Mechanics, Classical Mechanics, Collision Energy Protection of Momentum Kristin Favreau October 26, 1999 Reason: To show that energy is rationed in a shut framework by representing the preservation of force in a flexible crash and an inelastic impact. Technique: If force is saved in a shut framework, the all out energy of the framework before impact should approach the all out force of the framework after the crash. Strobe photographs will be utilized in the computations that will demonstrate that force is saved. 1.) Elastic crash: A strobe photograph will be utilized that shows a huge lightweight plane crushing into a littler lightweight plane which is at first very still. This will make the littler lightweight flyer move and the enormous lightweight flyer will keep on moving too. 2.) Inelastic crash: A strobe photograph will be utilized that shows a lightweight plane crushing into another lightweight flyer which is at first very still. At the point when they impact the two lightweight planes will remain together and will move. - The majority, separations and times will be estimated so as to compute the forces of the frameworks when crash happens. Information: V = d/t P = m x v 1.) Elastic impact: At the point when Mass Distance Time Velocity Momentum Lightweight flyer A Before Collision .31215 kg .009m .6s .015 m/s .00468 Kg m/s Lightweight flyer B Before Collision .15580 kg 0 m/s 0 Kg m/s Lightweight flyer An After Collision .31215 kg .005m 1.0s .005 m/s .00156 Kg m/s Lightweight flyer B After Collision .15580 kg .011m .6s .018 m/s .00280 Kg m/s 2.) Inelastic crash: At the point when Mass Distance Time Velocity Momentum Lightweight flyer C Before Collision .3105 kg .016m 1.0s .016 m/s .004968 Kg m/s Lightweight flyer D Before Collision .3000 kg 0 m/s 0 Kg m/s Lightweight flyers C+D After Collision .6105 kg .015m 2.0s .008 m/s .004884 Kg m/s Figurings: 1.) Elastic crash: Before After Lightweight flyer A .00468 Kg m/s .00156 Kg m/s Lightweight flyer B + 0 Kg m/s +.00280 Kg m/s .00468 Kg m/s .00436 Kg m/s 2.) Inelastic crash: Complete force before = Total energy after mv + mv = (m + m ) v (.3105kg x .016 m/s) + 0 = (.3105 kg + .3000 kg) x .008 m/s .0050 Kg m/s = .0049 Kg m/s End: Through trials with strobe photographs including versatile and inelastic crashes, I had the option to show that energy is contained inside a shut framework. My productivity for the versatile impact was 3.54% and my effectiveness for the inelastic crash was 1.01 %. Under 10 % of the force was lost in either crash showing a decent analysis. The lost force can be ascribed to the exchange from mechanical vitality to warm vitality. Wellsprings of Error: 1.) The separations estimated in the two strobe photographs were evaluated. 2.) The estimation of time was a normal. % mistake = contrast x 100 aggregate of all 1.) % mistake = .00032 x 100 = 3.54 % blunder .00904 2.) % mistake = .0001 x 100 = 1.01 % blunder .0099
