Force Essays - Physics, Mechanics, Classical Mechanics, Collision Force Preservation of Momentum Kristin Favreau October 26, 1999 Reason: To show that force is moderated in a shut framework by outlining the protection of energy in a flexible crash and an inelastic impact. Strategy: If energy is rationed in a shut framework, the all out force of the framework before impact should approach the absolute energy of the framework after the crash. Strobe photographs will be utilized in the counts that will demonstrate that force is rationed. 1.) Elastic impact: A strobe photograph will be utilized that shows a huge lightweight flyer 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 flyer crushing into another lightweight flyer which is at first very still. At the point when they impact the two lightweight flyers will stay together and will move. - The majority, separations and times will be estimated so as to ascertain 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 Computations: 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 impact: All out 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 investigations with strobe photographs including versatile and inelastic impacts, I had the option to show that energy is contained inside a shut framework. My effectiveness for the versatile crash was 3.54% and my proficiency for the inelastic impact was 1.01 %. Under 10 % of the force was lost in either impact showing a decent examination. The lost force can be credited 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
