Physical Science Project Energy Transfer and Conservation
Types of Energy 1. Mechanical. 2. Chemical. 3. Electrical. 4. Thermal. 5. Electromagnetic. 6. Nuclear.
What is MECHANICAL energy? �Energy that helps objects MOVE. �Two categories: Kinetic Energy Potential Energy Moving energy. Stored energy. �Mechanical energy puts something in motion.
What is MECHANICAL energy? � The bowling ball has MECHANICAL energy. � It rolls down the alley towards the pins… � When the ball strikes the pins, the mechanical energy is transferred.
What is MECHANICAL energy? Sound from vibrations
What is CHEMICAL energy? �Energy that is available from the release of CHEMICAL REACTIONS. �Chemical energy is the energy stored in food, wood, coal, petroleum and other fuels. �When these compounds are broken, the stored chemical energy is released in the form of HEAT or LIGHT.
What is CHEMICAL energy? � The CHEMICAL bonds in the match stick store energy. � That energy is released when you strike the match. � HEAT and LIGHT are both given off.
What is CHEMICAL energy?
What is ELECTRICAL energy? �Energy caused by MOVING ELECTRONS. �As a type of KINETIC ENERGY, electricity is produced when something upsets the balancing forces between protons and electrons in atoms. �Easily moved through power lines and converted to other forms of energy.
What is ELECTRICAL energy? � Electricity is made by a generator… � That generator sends the electricity through the power lines… � To your home/business where it is converted into something useful.
What is ELECTRICAL energy?
What is THERMAL energy? �Energy from MOVING PARTICLES. �As a type of KINETIC ENERGY, thermal energy is known as HEAT energy. �Thermal energy can do work for us, or be a result of doing work.
What is THERMAL energy? � The faster the molecules move… � The hotter an object becomes… � The more thermal energy is possesses.
What is THERMAL energy?
What is ELECTROMAGNETIC energy? �Energy from (visible or invisible) LIGHT. �Known as RADIANT energy, this category includes all waves. Radio, TV, infrared, visible, ultraviolet (UV), microwave, X-ray, Gamma ray.
What is ELECTROMAGNETIC energy?
What is NUCLEAR energy? �Energy locked in the NUCLEUS OF AN ATOM. �The force that bind the nucleus together. �Gives off HEAT and LIGHT. �The energy is released when the atoms… Combine together Split apart called FUSION. called FISSION.
What is NUCLEAR energy? Nuclear power plant SPLITS ATOMS = FISSION The Sun COMBINES ATOMS = FUSION
Law of Conservation of Energy. �Energy cannot be CREATED or DESTROYED. �It can only be ALTERED from one form to another. �Energy is recycled through the environment; it never spontaneously appears or disappears.
