1. Bell work
What do you think energy is?
(your definition)

2. Potential and Kinetic Energy

3. Objectives Explain the relationship between energy and work.
Compare kinetic energy and potential energy.
Describe the different forms of energy.

4. Energy Energy is the ability to do work.
Work is the transfer of energy from one object to another.
work = force × distance
Work and energy are expressed in joules.
There are two main types of energy that all others fall under-
Kinetic and Potential

5. Kinetic Energy Kinetic energy is the energy of motion.
                                                   
Kinetic energy is the energy of motion.
An object's kinetic energy can be found by the following equation:
The m stands for the object's mass in kilograms. The v stands for the object's speed.
The faster something is moving, the more kinetic energy it has.

6. Kinetic Energy
Visual Concepts

7. Objectives Explain the relationship between energy and work.
Compare kinetic energy and potential energy.
Describe the different forms of energy.

8. Potential Energy
Potential energy is energy based on an objects shape or position.
There are three main types of potential energy-
Gravitational potential
Elastic potential
Chemical potential

9. Gravitational potential energy
                                                                                                                         
Gravitational potential energy
Gravitational potential energy is based on position of height.
The amount of gravitational potential energy that an object has depends on its weight and its height.
You can find gravitational potential energy by using the following equation:

10. Gravitational potential energy
work = force × distance
Weight is the amount of force that you must use on an object to lift it, and height is a distance.
Weight is expressed in Newtons and height in meters, gravitational potential energy is expressed in Newton -meters (N•m), or joules (J).

11. Objectives Explain the relationship between energy and work.
Compare kinetic energy and potential energy.
Describe the different forms of energy.

12. Elastic potential energy
Elastic potential energy is the energy stored by an objects shape/position.
You change the shape of these objects by stretching them or compressing them.
The energy is released the object
goes back to its original
shape.

13. Chemical potential energy
Chemical potential energy is energy stored in the bonds of chemicals/substances- Such as food.
These chemical bonds are broken and release energy.
Eating food, burning wood/fossil fuels

14. Mechanical Energy
Mechanical energy is the amount of work an object can do because of the object’s kinetic and potential energies.
Mechanical energy can be all potential energy, all kinetic energy, or some of each.
You can use the following equation to find mechanical energy:
mechanical energy = potential energy + kinetic energy

15. Objectives Explain the relationship between energy and work.
