Sustainable energy, specifically renewable energy or green energy, is an energy source which can be replenished, that is essentially inexhaustible. Sustainable sources of energy include solar, wind, water, biomass and geothermal. Non renewable energy sources include coal, oil and natural gas. Water Energy The Generation of Electricity from Water Explain…

Concept of temperature The Term Temperature Define the term temperature Temperature is property of a body, which decides which way heat will flow when it is placed in contact with another body. The SI Unit of Temperature State the SI unit of temperature Temperature refers to the degree of coldness…

  1st law of Motion  The Concept of Inertia Explain the concept of inertia Inertia is the ability of a resting body to resist motion or a moving body to continue moving in a straight line when abruptly stopped. The more mass a body has, the greater its inertia and…

  Motion In Straight Line Motion is the change of position of an object from one place to another. There are two types of motions; i.Circular motion-Is the motion of an object in a circle. Examples; a/. motion of the electron around the nucleus of an atom b/.revolutionary movement of…

  Simple Machines A simple machine is a non-powered mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. A simple machine uses a single applied force to do…

  Moment of a Force The Effects of Turning Forces Explain the effects of turning forces A force is a push or pull which when applied to a body it will change its state either by stopping it if it was in motion or making it move if it was…

Concept of Magnetism The Orign of Magnetism Explain the origin of magnetism Chinese were the first to use the metal magnetite called lodestone. A Lodestone was capable of attracting small iron pieces and it was used as a crude navigation compass by Greeks. Lodestones were the earliest magnets. Iron, nickel…

  Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is…

Concept of Static Electricity The Concept of Static Electricity Explain the concept of static electricity Static electricity refers to the electric charges stored on a conductor. The Orign of Charges Explain the origin of charges When a plastic pen is rubbed with a cloth, it acquires the property of attracting…
