Chapter 5 Work, Energy and Power. Section 5.1 Work Work - The quantity of force times distance, as long as the force is parallel to the direction of motion.
Unit 3 EnergyandWork. Energy Energy is the ability to do work Energy is all around us There are two basic kinds of energy.
Energy Unit E, Chapter 3, Section 1, pE Energy – Energy: ability to cause changes in matter Objects, with energy can apply forces (push or pull)
What is energy?. WHAT IS ENERGY? Energy is the ability to do work. Work is done when a force causes an object to move in the direction of the force. Work.
WORK AND ENERGY Chapter 4. I.WORK AND MACHINES – 4.1 A.Definition of Work 1.Motion and work a.Please Define Work: Transfer of energy when a force is applied.
Chapter 9 Work and energy. Work What is work? What is work? To a scientist work is done when changing motion To a scientist work is done when changing.
ENERGY What is Energy? Ability to do WORK Measured in Joules (calories or kilocalories)
Energy: Forms and Changes. Nature of Energy EEnergy is all around you! You can hear energy as sound. You can see energy as light. And you can feel it.
Energy. Work Motion Direction Motion must be in the same direction of the apply force.
Work, Power and Energy Review Each table will work as a team to earn points by answering questions. There will be 60 seconds to answer each question from.
Work Work: Work is said to be done when the point of application of a force moves and it is measured using the product of force and the distance moved.
Energy is used everyday… Can you think of any examples?
Chapter 10: Work, Energy, and Simple Machines. Work No it’s not your job! Work is the product of force and the distance an object moves in the direction.
TOPIC: Energy AIM: Describe potential and kinetic energy and conversions that can occur between these two forms of energy. Do Now: Take out HW ditto Top.
Energy & Work. Work involves a change in a system. changing an objects position heating or cooling a building, generating a image on the TV screen, moving.
Conservation of Energy. Work To do work on an object you need an application of a force AND movement due to the force. Example: Lifting a barbell. A force.
Forms of Energy. QOD 1. What are the 5 types of energy? 2. Potential Energy and Kinetic Energy are examples of what type of energy?
Intro to Energy, Potential Energy, Kinetic Energy Karen Tino September 2013.
Work, Power, and Machines. What is Work? transfer of energy to a body by application of a force that causes body to move in direction of force. W = F.
Energy Energy: Energy is the capacity of a body to do work. The SI unit of energy is Joule(J) Chemical Energy Some forms of energy Sound Energy Light Energy.
Energy Part I Notes on the different types of energy.
KWLQ What is Energy? K: What do you know? W: What do you want to know? L: What did you learn? Q: What questions do you have?
