1. Energy Transformation

2. Energy Energy is the capacity or ability to do work
Work is the transfer of energy to an object by the application of a force that causes the object to move in the direction of the force
A force acting through a distance
Exerts a force over a distance to move an object
Work = force x distance

3. Units of Energy Force is measured in Newtons (N)
Distance is measured in meters (m)
Unit of work (energy) is a joule (J)
If you lift an object weighing 200N through 2.0m distance how much work did you do?
W = F x d
W = 200N x 2.0m
W = 400J
work F d

4. The distance an object moves must be in the same direction the force applied to the object for work to be done

5. Two Types of Energy
Kinetic energy (KE)
Potential energy (PE)

6. Potential Energy
Potential Energy (PE)- is the energy that an object has because of its position, shape, or condition of the object
Elastic PE
Stretched rubber band has potential to fly across room
Gravitational PE
Brick held above ground has potential to fall to ground

7. Kinetic Energy
Kinetic energy (KE)- is the energy of an object due to the object’s motion
All moving objects have kinetic energy
The faster an object moves and the more mass the greater its kinetic energy
Atoms and molecules have kinetic energy

8. 6 Forms OF ENERGY Chemical Electrical Mechanical Nuclear Radiant
Thermal

9. What is Mechanical Energy?
the amount of work an object can do because of the object’s KE and PE
The bowling ball has mechanical energy.
When the ball strikes the pins, mechanical energy is transferred to the pins!

10. What is Chemical Energy?
the energy that is released when a compound reacts to produce new compounds
Type of potential energy
Photosynthesis/ respiration

11. What is Electrical Energy?
Energy caused by the movement of electrons
Easily transported through power lines and converted into other forms of energy

12. What is Electromagnetic Energy?
Light energy
photosynthesis
Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands

13. What is Thermal Energy? Heat energy
The heat energy of an object determines how active its atoms are.
A hot object is one whose atoms and molecules are excited and show rapid movement.
A cooler object's molecules and atoms will show less movement.

14. The Law of Conservation of Energy
Energy cannot be created or destroyed, but may change from one form to another
Energy cannot appear or disappear
Energy can be transferred as work or heat
net change in energy = the energy transferred as work or heat
