The search for unification is currently very much dependent upon experimentation and raises questions as to the scientific validity of String Theory and whether it exists as science or philosophy — or indeed just an elegant, but meaningless, example of mathematical aesthetics.

Introduction The ultimate goal for physicists is to devise a unified theory, which describes the universe all in one go. However, this proves difficult — there are partial theories which do not fit together, each predicting a limiting number of observations and neglecting others.

Nevertheless the Standard Model exists as a framework for the coming together of partial theories. The electromagnetic force is stronger and is responsible for holding atoms and molecules together.

As with gravity, its range is infinite. The weak force and strong force are, by contrast, limited in range, and operate only within the dimensions typical of an atomic nucleus.

The weak force causes certain forms of radioactivity and Bouncing balls experiment coursework the nuclear fission reactions in the Sun.

The strong force binds quarks and antiquarks together within the particles we observe. It seems to act in such a way that quarks are always locked inside more complex particles and are never observed on their own. Gravity alone remains outside this model.

The problem with Gravity is that through the development of its theory, its existence in situations of different scale is neglected.

Newton proposed the first, classical, theory of gravity — but it failed to address some things — allowing crucial prediction but never offering an answer to why or how the universe worked like this. Einstein explained that Newton could provide only an approximation, revolutionising understanding with the theory of General Relativity.

But quantum mechanics and general relativity are incompatible — the major aim in physics today being to develop a model for gravity which incorporates them both.

Perhaps not, but inwhatever the relevance of the popularised apple anecdote, Isaac Newton questioned why objects fall perpendicularly to the ground.

What caused this downwards acceleration and was it the same for the rest of the universe? In the experiment a cannonball is fired from the top of a very tall mountain.

If there is no gravity the cannonball would continue in a straight line, but as with the apple — this is not the case. The greater the velocity with which the cannonball is fired, the further it travels before hitting the ground — this effect being compounded as the surface of the Earth curves away under the flight of the cannonball.

If the speed of the ball is equal to the threshold orbital velocity, it will continue circling the planet, like the moon.

The constantly changing velocity due to circular motion means the object is accelerating. If you move twice as far away from the Earth, for example, only one-quarter as much gravitational pull will be felt.

Welcome to Reddit,

The inverse square law already stood for describing how light energy spread out from a source over increasing distances, but Newton applied this to the acceleration of the moon. The acceleration of the moon towards the earth could be calculated.

If the orbit time is 2. This value squared and divided by radius 3. This is indeed the case as 9. The same equations could also be used to predict the orbit time correctly.

Mathematical proof could back the concept of universal gravity with the existence of a universal gravitational constant, G. However Newton was not entirely correct.

The McDonald Observatory boasts data which can map the orbit of the moon, for example, exact to cm.David Eager is the Professor of Risk Management and Injury Prevention and the Assistance Student Ombud at UTS.
