OK everyone get ready to learn a new vocabulary term.

Kinetic Energy Today we will be learning about kinetic energy,

Electrical Energy Electrical energy,

Mechanical Energy mechanical energy,

Thermal Energy And thermal energy.

Before we define these terms, let’s review some other words that you already learned, and make sure you are firm in your understanding.

Energy Today we are going to be learning about types of energy.

energy: ability to cause change Energy is the ability to cause change.

Energy Potential Energy Kinetic Energy Energy can be classified into 2 different categories. Kinetic Energy

potential energy: stored energy Potential energy is stored energy.

Energy Potential Energy Kinetic Energy Energy can be classified into 2 different categories. Today we will be focusing on Kinetic Energy. Kinetic Energy

kinetic energy Now, let’s define kinetic energy.

kinetic energy: energy from motion Kinetic energy is energy from motion.

Here, kinetic energy is shown in the bowling ball.

Kinetic energy is measured by mass,

and speed. speed

Now let’s pause for a moment to review the information we have covered already.

What is energy? What is energy? Provide wait time and give specific feedback based on student responses.

What is potential energy? Provide wait time and give specific feedback based on student responses.

What is kinetic energy? What is kinetic energy? Provide wait time and give specific feedback based on student responses.

Energy Kinetic Energy Electric Energy One type of kinetic energy we are going to focus on is electric energy.

electrical energy Now, let’s define electrical energy.

electrical energy: energy in an electric current Electrical energy is energy in an electric current.

electron There is energy in the circuit because electrons are moving.

In an electrified wire, electrons are moving from the negative side to positive side because of attraction.

Now let’s pause for a moment to review the information we have covered already.

Which kind of energy is found in an electric current? Sound Energy Electric Energy Chemical Energy Nuclear Energy Which kind of energy is found in an electric current?

This energy is found in an electric current? Sound Energy Electric Energy Chemical Energy Nuclear Energy Mechanical and Thermal

Energy Potential Energy Kinetic Energy Mechanical Energy Potential and kinetic energy can also combine to create mechanical and thermal energy. Mechanical Energy Thermal Energy

mechanical energy Now, let’s define mechanical energy.

mechanical energy: the total potential and kinetic energy in a system Mechanical energy is the total potential and kinetic energy in a system.

Mechanical energy is used to do work

Mechanical energy is based on motion and position

Potential Energy Kinetic Energy Mechanical Energy Mechanical energy is potential energy + kinetic energy

Energy Potential Energy Kinetic Energy Mechanical Energy Potential and Kinetic energy can also combine to create thermal energy. Mechanical Energy Thermal Energy

thermal energy Now, let’s define electrical energy.

thermal energy: the combined potential and kinetic energy of a particle Thermal energy is the potential and kinetic energy of a particle.

Here we are looking at heat Here we are looking at heat. Blue is read on the gun when an item is colder.

Red is seen on the gun when an item is hotter and moving faster.

Now let’s review the information we have covered today.

What is kinetic energy? What is kinetic energy?

Mechanical energy is based on _____ and ______? Mechanical energy is based on (position) and (motion).

Which type of kinetic energy is found in an electric current? Potential Thermal Electrical Chemical Which type of kinetic energy is found in an electric current?

Which type of kinetic energy is found in an electric current? Potential Thermal Electrical Chemical Electrical energy is found in an electric current.

Remember!!! So remember!

kinetic energy: energy from motion Kinetic energy is energy from motion.

electrical energy: energy in an electric current Electrical energy is energy in an electric current.

mechanical energy: the total potential and kinetic energy in a system Mechanical energy is the total potential and kinetic energy in a system.

thermal energy: the combined potential and kinetic energy of a particle Thermal energy is the potential and kinetic energy of a particle.
