FORCES WHICH GOVERN OUR UNIVERSE

FORCES WHICH GOVERN OUR UNIVERSE Everything which occurs in our universe is basically governed by four different kinds of forces. Gravity: Einstein and Newton. Explanation. Electromagnetic Force: Maxwell. Explanation. Nuclear Forces: Atoms, Weak and Strong Nuclear Forces. Summary. INTRODUCTION The explanation for all processes which take place in our universe is basically that there are four kinds of fundamental forces. Gravitational Force. Einstein and Newton. What is the gravitational force? Weight. Gravitational acceleration. Electromagnetic Force Electromagnetism. Electrons. Storms. Electrical charges of the same sign repel one another, whereas different signs attract. Electromagnetic force. Compasses. Maxwell: magnetism and electricity are one and the same thing. Electronic force is responsible for the majority of things in the world that surrounds us. Nuclear forces All bodies which exist in the Cosmos are all made up of atoms. The atom’s nucleus: neutrons, protons, strong nuclear force. The energy produced by these forces is that which generates the light and warmth of the sun. Atomic bombs. Weak nuclear energy. Natural radioactivity. Strong nuclear energy. Nuclear power plants. The most important challenge to physicists in our day-and-age is to find a theory which would govern these four fundamental forces in nature. SUMMARY
