Trying to build a perpetuum mobile
... first principle of thermodynamics or the energy conservation law. This law says that it is impossible for a system to consume more energy than it has. For a general transformation this law is written: -W=E(a)-E(b),where W is the mechanical work and E(a) and ...
GCSE, Physics: What affects the resistance of a piece of wire?
... electric circuit or part of a circuit that transforms electric energy into heat energy in opposing electric current. Resistance involves collisions of the current-carrying charged particles with fixed particles that make up the structure of the conductors. This diagram shows that the ions ...
Albert Einstein
... electric machinery. He did not talk until the age of three, but even as a youth he showed about nature and an ability to understand difficult mathematical concepts. Einstein hated the dull and unimaginative spirit of school in Munich. When repeated business failure led the family to leave Germany ...
Basic physics of rowing
... Resistance 3. Kinetic Energy 4. Centre of Mass 5. Speed Variation 6. Balance 7. Levers 8. Gearing 9. Appendix: Newton's Laws of Motion 1. Propulsion A boat accelerates through the action/reaction principle ...
Factors affecting the stretching of springs and rubber bands
... and windows must be closed. Safety While doing the experiment it is important to consider aspect of safety. To ensure the experiment is carried out in a safe way I have to firstly tie back long hair and lose clothing to prevent distractions and interference and ...
An essay describing why water/gallium expand when frozen.
... . As the water freezes, it freezes from top to bottom, and outside to inside. First the surface freezes from the sides, leaving a tiny hole in ... both when heated and cooled. Not only is the explanation reasonable, but the effects of this odd property have their own advantages and disadvantages as well ...
Bug up physics coursework
... energy given to the bug up toy is being spent on the making of sound and the spinning in the air. Spinning in the air can be prevented by putting some weight to stabilize the toy in the air. And ... first one will be for the mass of bug-up, the next four will show the height of the jump, and ...
Centripetal and Centrifugal - To find out in which direction an object flies off, if it is spun and then released and to investigate how the radius affects the speed of ta spinning object.
... the object spin. 5) Keep the object spinning at a constant force or speed. 6) Let go of the string and observe what happens. Procedure B: 1) Do steps 1 - 5 in procedure A. 2) As the object comes around, place ...
Contrasting the viewpoints between aristotle and galileo methods
... a heavier object's acceleration being greater than that of a lighter one is a qualitative observation. Along with his logical reasoning, his generalizations were considered the authority for the time. In Galileo's time, the use of mathematical calculations and quantitative analysis were used ...
The Science Of Soccer
... motion until another force stops it. Newton's 2nd law is the equation force times mass = acceleration. For example: if the ball is kicked with 80 newtons of force, and the ball weighs .45 kilograms the ball would be traveling 36 kilometers per ...
