OK everyone get ready to learn a new vocabulary term.
2
Kinetic Energy Today we will be learning about kinetic energy,
3
Electrical Energy Electrical energy,
4
Mechanical Energy mechanical energy,
5
Thermal Energy And thermal energy.
6
Before we define these terms, let’s review some other words that you already learned, and make sure you are firm in your understanding.
7
Energy Today we are going to be learning about types of energy.
8
energy: ability to cause change
Energy is the ability to cause change.
9
Energy Potential Energy Kinetic Energy
Energy can be classified into 2 different categories. Kinetic Energy
10
potential energy: stored energy
Potential energy is stored energy.
11
Energy Potential Energy Kinetic Energy
Energy can be classified into 2 different categories. Today we will be focusing on Kinetic Energy. Kinetic Energy
12
kinetic energy Now, let’s define kinetic energy.
13
kinetic energy: energy from motion
Kinetic energy is energy from motion.
14
Here, kinetic energy is shown in the bowling ball.
15
Kinetic energy is measured by mass,
16
and speed. speed
17
Now let’s pause for a moment to review the information we have covered already.
18
What is energy? What is energy?
Provide wait time and give specific feedback based on student responses.
19
What is potential energy?
Provide wait time and give specific feedback based on student responses.
20
What is kinetic energy? What is kinetic energy?
Provide wait time and give specific feedback based on student responses.
21
Energy Kinetic Energy Electric Energy
One type of kinetic energy we are going to focus on is electric energy.
22
electrical energy Now, let’s define electrical energy.
23
electrical energy: energy in an electric current
Electrical energy is energy in an electric current.
24
electron There is energy in the circuit because electrons are moving.
25
In an electrified wire, electrons are moving from the negative side to positive side because of attraction.
26
Now let’s pause for a moment to review the information we have covered already.
27
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?
28
This energy is found in an
electric current? Sound Energy Electric Energy Chemical Energy Nuclear Energy Mechanical and Thermal
29
Energy Potential Energy Kinetic Energy Mechanical Energy
Potential and kinetic energy can also combine to create mechanical and thermal energy. Mechanical Energy Thermal Energy
30
mechanical energy Now, let’s define mechanical energy.
31
mechanical energy: the total potential and kinetic energy in a system
Mechanical energy is the total potential and kinetic energy in a system.
32
Mechanical energy is used to do work
33
Mechanical energy is based on motion and position
34
Potential Energy Kinetic Energy Mechanical Energy
Mechanical energy is potential energy + kinetic energy
35
Energy Potential Energy Kinetic Energy Mechanical Energy
Potential and Kinetic energy can also combine to create thermal energy. Mechanical Energy Thermal Energy
36
thermal energy Now, let’s define electrical energy.
37
thermal energy: the combined potential and kinetic energy of a particle
Thermal energy is the potential and kinetic energy of a particle.
38
Here we are looking at heat
Here we are looking at heat. Blue is read on the gun when an item is colder.
39
Red is seen on the gun when an item is hotter and moving faster.
40
Now let’s review the information we have covered today.
41
What is kinetic energy? What is kinetic energy?
42
Mechanical energy is based on
_____ and ______? Mechanical energy is based on (position) and (motion).
