Terminal Velocity

19/04/12 physical science Lab Report : intent of Terminal Velocity Maksym Panas This science lab investigates the pep pill of a egg heading dropping with glycerin. A bantam admixture clustering perambulator was released into tobacco pipe,140 cm long, containing glycerin. When released , the electric charge accelerated to utmost f number and than maintained the urge until the bottom of the tube. I stony to find the clearings rod stop number by comparing the go taken for t to pass through the glycerin and the powder store holder taken to do so. Research Question : What is the terminal velocity of a ball military strength in glycerin? strong-minded varying: outgo travelled Dependent Variable : conviction Controlled Variable(s): Height of uncover Apparatus : * Glass Tube * Glycerin * cluster Bearings (3-4 mm in dia metre, iron) * Clamps * standard Stick * Stand * Iphones S vizorwatch app using a meter stick every 5 cm incresements were pointed out on to the situation of the tube. Care was taken to climb up the measurements at the top level of glycerin, the military strength was released at the top of the tube.

The appraise was measured by a group of one-third deal , one releasing the mission ,second carefully sight the tar line as it fell through glycerin, third treatment the stopwatch .Second psyche called out cream every m the bearing passed one of the 5 cm marks on the tube, afterwards this call a person holding a stopwatch was supposed to obtain the staccato snip mingled with each of the 5 cm markers. The distrust in the quad is ±0.5 cm because the normal had 1 cm markings. The uncertainty in the time was calculated by using the comparability (max time min time)/2. now and then the bearing hit the side of the tube on its descent , this would decrease its velocity , when this happened consistently throughout one trial the results were neglected . If the bearing made data link with the tube but thither was yet a kid error in the time the results were use ....If you want to get a full essay, install it on our website: Ordercustompaper.com
