## Physics with the decrease in either pressure or

Physics Internal Assessment   Investigation between the height of water level, range of jet and discharge                           Introduction I have been always fascinated with water and the way it functions. Of course, back in time this wasn’t expressed through principles…

## In Energy is also responsible for the shape

In 1929 Edwin Hubble made the assumption that space could be expanding in some way, because in distant planets the light began to shift . Even before that Albert Einstein discovered something called the cosmological constant.He considered the constant a source for Vacuum energy. This source turned out to be something called Dark Energy &…

## The force f is f = ma. Acceleration

The Mathematician               Isaac Newton was born January 4, 1643, Woolsthorpe Manor, United Kingdom. The English physics studied the basic force of gravity and is one of the world’s greatest scientist. But, beneath his truth was a story never to be spoken of. Newton made discoveries in optics, motion, and mathematics. Newton thought…

## 2. can be stated as a theorem. Theorem.

2. The two-site resistance : a theorem   Consider an infinite lattice structure that is a uniform tiling of  resistors. Let is the number of lattice sites in the unit cell of the lattice and labeled by . If the position vector of a unit cell in the  is given by , where  are the unit cell vectors and  are integers. then, each lattice site can…

## Resistance Of A Wire

For my GCSE physics coursework I intend to investigate the resistance of a wire and specifically how the length of the wire affects the resistance.Firstly I shall do some initial research to determine what resistance is, what affects it in general and anything else that I think will be relevant to my investigation.Then I will…

## “Finding the resistance of nickel chrome wire by calculating the current”

N.B: My results in these experiments are shared with my classmate, John Morgan, as we worked together on this investigation.IntroductionThis experiment has been set up in order to find the resistance of a nickel chrome wire when a current is passed through a series circuit. The resistance is calculated by using Ohm’s law of:Resistance =…

## Investigation of Flow rate and temperature difference

My coursework is based on the principle of how an electric shower works. The common assumption is that in order to alter the temperature i.e. increase or decrease it, there is a heating implement in place which does this, but my investigation has proven this is not the variable. There is a heating implement but…

## Period of Oscillation of a Simple Pendulum

Aim: to consider the time taken for a pendulum released from angle until it gets back to the point where it was released i.e. period and hence the effective factors such as : mass, angle, gravity ,viscosity and length. So I will consider each separately.Hypothesis: in physics we have a formula called Galileo’s formula stating:T…

## Physics Coursework

I aim to collect two sets of data in my physics coursework both will observe the stopping distances of toy cars travelling down a ramp. The first will be to see the affect of a change in mass on the car to the stopping distance. The second will observe the affects of the height of…
