Ivan liu natural philosophy Motion PRAC 7 Motion PRAC 7: Air cover up Sticky bang presentment: In a gluey opposition, a glider from the go forth is moved towards a nonmoving glider on the right. It collides with the stationary glider and they move away together at a common speed. The single flyer on the left go across glider can be used to greenback the downward speed of the left hand glider forwards and the common speed of both gliders by and bywardswards the shock. Aim: tally the different effects to pulsation when a light practice collides with a heavy object and criminality versa. Hypothesis: The heavier object, after colliding into the light glider will prolong kinetic massiveness amend than a igniter object colliding into the heavier glider setup: Refer to CGS Physics whole 1 Prac check 2011 p.19-20 Method: Refer to CGS Physics Unit 1 Prac Book 2011 p.

It was shown that Kinetic energy is conserved better when the heavier glider collides into the lighter one (37.9%) than the other way just about (10.5%). However, these results whitethorn not be entirely correct cod to errors and factors which may affect the results and the experiment process itself. Some of these include friction,...If you wishing to get a full essay, order it on our website: OrderCustomPaper.com
