Chapter 5 Work, Energy and Power
Work, Energy, & Power. Work Work (in science) is calculated by multiplying the force by the distance through which the force is applied. W (Joule) = F.
Chapter 5: Work, Energy, & Power Section 5.1: Work pages 83 to 86 Section 5.2: Energy Conservation pages 87 to 90 Sections 5.3: Energy Transformations.
Chapter 5 Review Work may be measured using units of: Joules.
Chapter 12 Review Work and Energy.

Unit 3 Energy and Work.
8 th Grade. The ability to do work is called A. velocity B. energy C. conversion D. friction B.
CHAPTER 2 ENERGY. 1. Visible light is an example of Electromagnetic energy 2. Change from one energy form to another is Energy transformation.
Energy - The Ability To Cause Change -. Kinetic Energy energy due to motion Kinetic Energy and Speed the faster an object moves, the more kinetic.
Work and Energy By Mr Leavings Chapter 5. What is Work In science Work has a specific meaning. If you push a box with a force of one newton for a distance.
Energy Energy is a quantity that measures the ability to cause change in an object or system. We get energy from the changes in food when it is digested.

Work, Power and Energy.
Do Now Nov. 4th In your Do Now Book, list ways that you used energy this morning.
Work, Machines and Energy Systems Reference: Ch. 10 & 11.
Work & Energy Chapter 12 Notes. Work / Work has a specific meaning in science - Work is done when a force causes a change in the position of an object.
Work = work is done when a net force on an object causes it to move a distance W = Fd Or Work (measured in joules) = Force (N) times Distance (m) Is work.
ENERGY REVIEW. What is energy? The ability to do work or make change in matter.
Chapter 5 ENERGY. What is the ability to do work? 1.Kinetic energy 2.Potential energy 3.Mechanical energy 4.Energy.
Work and Power Notes What Work and Power are not… Work is not where you go to earn a check! Power is not how strong you are!
1. 2 Work: done ONLY when a force is applied to an object, and the object moves IN THE SAME DIRECTION OF THE APPLIED FORCE Work is calculated by multiplying.
Work and Energy. What is WORK? Work is equal to the amount of force it takes for an object to move a distance. Formula: Work = Force X Distance W = F.
The Law of Conservation of Energy Energy cannot be created or destroyed. E= m x C 2.
Forms and Transformations
Which of the following is a conversion from light energy to chemical energy? A. Turning on a stove to heat dinner. B. Making toast in a toaster. C. Growing.
Heat = mass X change in temp X specific heat 1.10 g X 33 o C X 0.90 J/g o C = 297 J g X T X 0.50 J/g o C = 5275 J 1.25 T = 5275 – divide both.
Chapter 5 Work, Energy and Power p. 79. Work “Work” means many things in different situations. When we talk about work in physics we are talking about.
L3 Energy and Power To discuss energy, we first discuss the concept work done on an object. Work done is defined as the product of a force exerted on.
Energy Physics 4 th Six Weeks. What is Energy? Energy is defined as the ability to produce a force. Energy is also defined as the ability to cause a change.
What is energy?. Energy- the ability to do work When one object does work on another object, energy is transferred from the first object to the second.
Chapter 6:. 1) Energy is a measure of the ability to cause change or to do “work.”
Our BIG question: HOW MUCH ENERGY IS IN AN EARTHQUAKE ?
ENERGY The stuff that makes things go.. What is Energy? - Energy = The ability to do work or cause a change in motion. -Measured in Joules (J) & calories.
Unit 2 Energy. Energy Transformations Law of Conservation of Energy Energy cannot be created or destroyed only transformed to another type of Energy.
How do we define Energy? The ability to do work & cause a change. Unit of measurement is the Joule ( J ) Examples of how we use energy: – cars move, bake.
