 without light and radiant energy from the Sun we would not have life on Earth  its energy is needed for plants to grow, the atmosphere to circulate,

 Thermal energy is the energy that is associated with the motion of the particles in a substance.  All matter is made up of atoms (particles) that move.

Book M: Section 5.1. When wind moves a leaf, or even a house, it causes a change. In this case, the change is in the position of the object. Recall that.

Potential and Kinetic Energy doesn’t just “appear” it comes from something or some other form.

It makes things happen!!. What is ENERGY? We have all heard the term energy, but what exactly is it? ENERGY is defined as “the ability to do work.” In.

Energy: its forms and uses

How do we define Energy? The ability to do work & cause a change. Unit of measurement is the Joule ( J ) Examples of how we use energy: – cars move, bake.

Forms and Types of Energy Energy: The property of an object that allows it to produce change in the environment or in itself. (The ABILITY to do WORK)

Lesson 3: Energy Transformations Review

Energy is said to be the ability to do work. That means the ability to make something happen. By “happen” it means to make things move or change condition.

Kinetic and Potential Energy have many forms. 1. Mechanical Energy - Energy associated with motion or position.

Forms of Energy. Nature of Energy Energy is the ability to do work. If an object or organism does work, then it uses energy. Work is the use of a force.

Remember… all forms of energy are either kinetic or potential.

Energy Transfer & Transformations How does energy impact the motion of an object?

ENERGY Ability to do work or cause change. Potential Stored energy. Has the ability to move. It might move, it might not move.

 Energy is the ability to do work or cause change.  Work is done when a force moves an object through a distance. Work is the transfer of energy. (The.

Energy Basics. Energy The ability to do work or cause change Either potential or kinetic.

Chemical Energy is energy stored in the bonds of atoms and molecules. Biomass, petroleum, natural gas, and coal are examples of stored chemical energy.

By Smiley Teacher TPT. Energy can be put into 2 categories:

Sun Source of almost all the energy is the… Wood, coal, petroleum and natural gas come from the sun. The USA gets 90% of its energy from fossil fuel.

Energy Foldable Types, Forms and Energy Transformations.

Energy is said to be the ability to do work. That means the ability to make something happen. By “happen” it means to make things move or change condition.

 Transfer of energy by electromagnetic waves  Heat moving in the form of waves  Example: Sun heating Earth’s surface.

Energy Basics. Energy The ability to do work or cause change Either potential or kinetic.

 Energy= the ability to do work, measure in Joules (J)  Work- the transfer of energy 2 types of energy: 1. kinetic energy 2. potential energy.

ENERGY – is the ability to do work or cause change Work is a transfer of energy. When energy is transferred, the object upon which work is done gains.

Gravitational Potential Energy Picture: Type: Gravitational Potential Energy Picture: Boulder on a cliff, book on a shelf What is it? energy of an object that has been lifted or elevated How is it used? weight x height

Elastic Potential Energy Picture: Type: Elastic Potential Energy Picture: Rubber bands, Slinky, springs, bow and arrow What is it? energy that is stored in stretched out items How is it used? an object gains EPE as it is stretched out

Thermal Energy - Thermal energy is made and measured by heat of any kind. It is caused by the increased activity of molecules in something which causes the temperature to rise. There are many natural sources of thermal energy on Earth.

Heat from moving molecules How is it used? Type: Thermal Energy Picture: Sun, fire, iron, candle What is it? Heat from moving molecules How is it used? -heater -toaster -stove/oven -iron

Chemical Energy - a form of potential energy and it is possessed by things such as food, fuels and batteries. As chemical reactions happen, this energy is released.

stored energy in chemical compounds How is it used? Type: Chemical Energy Picture: Battery, food, gasoline, fireworks What is it? stored energy in chemical compounds How is it used? -batteries -gasoline -food -fireworks

Mechanical Energy -Mechanical energy describes the energy in a mechanical system. This energy includes both kinetic energy, the energy of motion, and potential energy, the stored energy of position.

energy of motion and position = potential energy + kinetic energy Type: Mechanical Energy Picture: Bicycle, car, windmill, fan, Ferris wheel What is it? energy of motion and position = potential energy + kinetic energy How is it used? -bicycle -turbine -fan -car

Electrical Energy - Electrical energy is the presence and flow of an electric charge through something such as a wire or circuit.

-moving electrons - objects with a plug or battery Type: Electrical Energy Picture: TV, computer, cell phone What is it? -moving electrons - objects with a plug or battery How is it used? -TV -computers -cell phones -XBox

Radiant Energy (Light Energy)-Energy that comes from electromagnetic waves is called radiant energy. Electromagnetic waves take many forms, from microwaves to x-rays to visible light.

-vibration of electrically charged particles -can be seen Type: Light Energy Picture: Light bulb, sun, fire What is it? -vibration of electrically charged particles -can be seen How is it used? -sun -light bulb -fire

Sound Energy- Sound energy is the energy produced by sound vibrations as they travel through a solid, liquid or gas. Sound vibrations cause waves.

vibrating particles cause waves How is it used? Type: Sound Energy Picture: Music, talking, TV What is it? vibrating particles cause waves How is it used? -music -talking -TV -SONAR
