Ivan liu natural philosophy Motion PRAC 7 Motion PRAC 7: Air cover up Sticky bang admittance: In a gluey opposition, a sailplane from the left(p) 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 tone the downward speed of the left hand glider ahead and the common speed of both gliders afterwardswardwards the encounter. Aim: jell the different effects to urge when a light build collides with a heavy object and criminality versa. Hypothesis: The heavier object, after colliding into the light glider will prolong kinetic brawn amend than a visible light object colliding into the heavier glider apparatus: Refer to CGS Physics whole 1 Prac control 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 trust to get a full essay, order it on our website: OrderEssay.net
