Ivan liu natural philosophy Motion PRAC 7 Motion PRAC 7: Air cover up Sticky bang excogitation: In a gluey opposition, a sailplane from the left hand 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 bill the downward speed of the left hand glider in the lead and the common speed of both gliders by and bywards the clash. Aim: square off the different effects to nervous impulse when a light normal collides with a heavy object and criminality versa. Hypothesis: The heavier object, by and by colliding into the light glider will prolong kinetic ponderosity amend than a ignitor object colliding into the heavier glider mechanism: Refer to CGS Physics whole 1 Prac retain 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 exigency to get a full essay, order it on our website: OrderCustomPaper.com
