Forms of Energy

Forms of Energy

by Dominique Pandy

​Lesson Frame

​We will differentiate among forms of energy, including mechanical, sound, electrical, light, and thermal (heat).

​

​I will give an example of mechanical energy.

Open Ended

What are some things that use energy?

​What is Energy?

​​The ability to cause change in matter.

​Anything that moves has energy

​Types of Energy

​Note Title: Energy

​How does Mechanical Energy Work?

​Something in motion has kinetic energy. Kinetic energy is the energy of motion.

​

​This roller coaster is on top of the hill has potential energy.

​

​Mechanical energy is the total potential energy and kinetic energy of an object.

Multiple Choice

The energy something has because of its position, such as a roller coaster on top of a hill:

• Potential Energy

• Light Energy

• Sound Energy

• Heat Energy

Multiple Choice

When a ball sits on top of a hill it has: 

• Potential Energy

• Light Energy

• Sound Energy

• Heat Energy

​What is Electrical Energy?

​A form of energy that comes from electric current. Electrical energy provides the energy for most of the devices we use, including this computer.

​What is Light Energy?

Light energy travels in waves. This form of energy is one that we can see.

​

​Why is it important?

Light can help us see things like a night light in the dark or car headlights when

Multiple Choice

Which example best represents light energy?

• Shining a flashlight in a dark room. 

​What is Thermal Energy?

​Thermal energy is the total Kinetic energy of particles in a substance. The faster the particles in a substance move, the more thermal energy the substance has.

​

​Cool hand become warm when rubbed together. Try it!

​

​HEAT ENERGY- Is different: it is energy that moves between objects at different temperatures.

​What is Sound Energy?

​A type of energy made by vibration

​

​Vibrations make sound waves

Multiple Choice

• A ball on a hill 

• A plugged in laptop

• playing an instrument such as a flute. 

• Hands rubbing together
