What Factors affect the resistance of a piece of wire(evaluation missing)
... of the free moving electrons being resisted by the atoms in the wire. In a longer piece of wire, there would be more atoms for the electrons to collide with and so the resistance would be greater. The relationship between the wire length and the resistance should be directly proportional ...
The IB Physics THERMAL PHYSICS
... internal energy and heat Temperature This is ususally measured in degrees Celsius or oC where the freezing point of water is 0 oC and the boiling point is + 100 oC. We have taken observable physical phenomena for the substance water, and comibined with something that changes in the interval ...
James Chadwick
... great education. They were educated in the fields of natural sciences and also humanities, this was all done by private first class teachers. He died at his home in Italy in December of 1896. A man that was so smart and gifted died of a cerebral hemorrhage ...
This information on different types of gears. I had to do a speech about gears. Thought it might be useful for someone else.
... in the opposite direction to the driving gear and therefore turns the driven gear in the same direction as the driving gear. In any form of gearing the speed of the driven shaft depends on the number of teeth in ...
Physics Coursework Theory - The resistance of a wire.
... in the wire gain kinetic energy and start to vibrate. As their motion becomes more erratic they are more likely to get in the way and disrupt the flow of the electrons and therefore increase the resistance. Length of ...
Potential Energy
... The balls potential energy was high at the top of the ramp, and the balls kinetic energy was low at the top of the ramp. As the ball rolled down the ramp its potential energy decreased and the kinetic energy increased. When the height of the ramp ...
Nothing is certain
... of an atom for more than a fraction of ... In the movie “The Ascent of Man” the narrator points out that the goal of physical science is to paint an exact picture of all material, in the same sentence he says that the crowning achievement of ...
Electromagnetic Radiation
... of energy. Also each photon has a certain amount of energy, except for gamma rays, all electromagnetic radiation is generated by the movement of electrons, negatively charged particles in the atoms of a substance. Which in that case electrons emit photons.The electromagnetic wave is made up of ...
