"Energy and its Forms" PPT

Description

"Energy and its Forms" PPT

Part One: Learning Objectives

1. Know the various forms of energy that exist in nature such as mechanical energy, light energy, thermal energy, electrical energy, chemical energy, solar energy, nuclear energy, etc.

2. Be able to analyze the existence form of energy in specific situations.

Thoughts and discussions:

1. The cyclist uses his feet to pedal the bicycle pedal to provide energy to make the bicycle move.

2. Solar cars use the energy of the sun to convert into electrical energy to run the motor in the car and move the car forward.

3. The tram uses electricity to move the car.

4. The rotation of windmill blades is driven by wind energy.

Energy and its forms PPT, part 2: understanding energy

Any object requires energy to work

definition:

Energy, referred to as "energy", refers to the properties of matter and its motion measured by the ability to work.

The ability to make an object "work" or move is called energy.

Energy and its forms PPT, Part 3: Forms of energy

What form of energy does the phenomenon pictured below have?

In some common phenomena, there are different energy forms, such as sound, light, electricity, heat, magnetism, tidal energy, etc.

Other forms of energy include: wind energy, mechanical energy, solar energy, nuclear energy, biological energy and geothermal energy.

different forms of energy

chemical energy

A form of energy stored in matter that is released and converted into other energy when the matter is burned or otherwise changed in nature (a chemical reaction occurs)

thermal energy

The more thermal energy an object has, the higher its temperature.

light energy

Lamps, flashlights, televisions, etc. all emit light energy. The sun is a star that emits a lot of light energy

sound energy

Objects emit sound energy when they are struck or vibrated.

Energy and its forms PPT, part 4 content: Class summary:

Energy: The ability to make objects "work" or move is called energy.

In some common phenomena, there are different energy forms, such as sound, light, electricity, heat, magnetism, tidal energy, etc.

Apart from this, what other energies can you name?

group discussion

Energy is universal. What would happen to the world if there was a lack of certain energy?
