The History of Sustainable Development The basic principles of sustainable development for human settlements‚ townships and boroughs enjoy great popularity and they are likely to have been contrived and introduced for the 1st time by scientific community and public activists striving for better life of common people. They are disseminated all over the world due to the activities and measures taken by the United Nations. In the year of 1983 The World Commission on Environment and Development

Kinetic Energy: Consider a baseball flying through the air. The ball is said to have "kinetic energy" by virtue of the fact that its in motion relative to the ground. You can see that it is has energy because it can do "work" on an object on the ground if it collides with it (either by pushing on it and/or damaging it during the collision). The formula for Kinetic energy‚ and for some of the other forms of energy described in this section will‚ is given in a later section of this primer. Potential

Examples of Radiant Energy The term radiant energy refers to energy that travels by waves or particles‚ particularly electromagnetic radiation such as heat or x-rays. Radiant energy is created through electromagnetic waves and was discovered in 1885 by Sir William Crookes. Fields in which this terminology is most often used are telecommunications‚ heating‚ radiometry‚ lighting‚ and in terms of energy created from the sun. Radiant energy is measured in joules.

Types of Energy: Energy is the ability to do work and there are many types of energy. Mechanical Energy is the energy of motion that does the work like the wind turns a windmill. In physics‚ mechanical energy is the sum of potential energy and kinetic energy present in the components of a mechanical system. It is the energy associated with the motion and position of an object. The law of conservation of energy states that in an isolated system that is only subject to conservative forces‚ like

Changes Toward a Sustainable Society Steven Aulisio Changes Toward a Sustainable Society As mankind strives for advancement we learn from the old ways where we have stumbled in our past. We also adhere to the same mindset as we have in the past as well. As we learn from our past mistakes the changes toward a sustainable society become a reality but we are held back by the same unsustainable way of thinking. Technology which was once destructive to the environment

Forms of Energy CHEMICAL Energy Chemical energy is stored in the bonds between atoms. This stored energy is released and absorbed when bonds are broken and new bonds are formed – chemical reactions. Chemical reactions change the way atoms are arranged. NUCLEAR Energy Nuclear energy is the stored potential of the nucleus‚ or center‚ of an individual atom. Most atoms are stable on Earth; they retain their identities as particular elements‚ like hydrogen‚ helium‚ iron‚ and carbon‚ as identified

Heat energy Temperature – measure of the average KE of the particles in a substance‚ measured in degrees Celsius or degrees Kelvin. Celsius 0⁰C (freezing point of water) to 100⁰C (boiling point of water) Kelvin 0 K (absolute zero‚ particles stop moving theoretically)‚ equivalent to -273.15⁰C. Uses the same scale for increase‚ ie. a 1⁰C increase in temperature equates to a 1K increase in temperature. Heat – amount of energy transferred‚ measured in Joules (J) Kinetic Energy‚ Thermal

Lab #7: Thermal Energy Heat is thermal energy being transferred from one place to another‚ because of temperature changes. This can take place by three processes. These three processes are known as conduction‚ convection‚ and radiation. When we place two objects with different temperatures in contact with each other‚ the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while
