Potential and Kinetic Energy
How is all energy divided?Potential Energy Kinetic Energy Gravitation Potential Energy Elastic Chemical
What is Potential Energy?Energy that is stored and waiting to be used later
What is Gravitational Potential Energy?Potential energy due to an object’s position P.E. = mass x height x gravity Don’t look down, Rover! Good boy!
What is Elastic Potential Energy?Potential energy due compression or expansion of an elastic object. Notice the ball compressing and expanding
What is Chemical Potential Energy?Potential energy stored within the chemical bonds of an object
What is Kinetic Energy? Energy an object has due to its motionK.E. = 1/2mv2
Kinetic Energy Depends on 2 factorsMass and Velocity If Dino and the car have the same velocity, which has the greater KE? If the trucks have the same mass, which one has greater KE?
Which factor has the greater impact on KE?Think about the formula!! Velocity has greater influence because it is SQUARED in the formula!!
Energy is Conserved!
The total amt of energy remains constant!!KE i + PE i = KE f + PE f
TME = KE + PE Mechanical EnergyThe total amount of KE and PE is referred to as the total MECHANICAL ENERGY of an object. TME = KE + PE
There are other forms of energy.

Mechanical Energy Ch. 4. Energy Is the ability to do work. Energy = work Units = Joules (J) James Prescott Joule.
Potential and Kinetic Energy Understanding the cyclic nature of potential and kinetic energy.
Unit 2 Lesson 2 Kinetic and Potential Energy
STORED ENERGY Wood is stored chemical energy until it is burned and the potential energy is released. A ball held above the ground has potential energy.
The Nature of Energy Section 4.1. Energy Every change that occurs involves. Every change that occurs involves. Moving objects have energy Moving objects.
Potential Energy Stored energy due to the relative position of an object In the field of a field force (i.e., gravity, electrostatic, magnetic) In relation.
Chapter 15 Sections 1-2. Energy is the ability to do work. Energy is measured in Joules, just like work.
Energy Note Outline Energy is the ability to perform work Units for energy is Joules (J)--kgm²/s².
Work and Energy Ch. 9.3 What is Energy?. Section 9.3 Objectives Explain the relationship between energy and work. Define potential energy and kinetic.
SP1.Students will analyze the forms and transformations of energy.
The Law of Conservation of Energy
Chapter 4 Energy
Kinetic and Potential Energy
Work and Energy Physics 1. The Purpose of a Force The application of a force on an object is done with the goal of changing the motion of the object.
Work is only done by a force on an object if the force causes the object to move in the direction of the force. Objects that are at rest may have many.
Unit 5 – Lecture 1. Energy Energy – the ability to do work the ability to cause change measured in joules symbol: [as in.. E = mc 2 ] E.
Work is the product of a force moving an object a given distance.
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.
Energy Kinetic energy is the energy of motion. Potential pnergy is stored energy.
Energy In all it’s forms. What is energy? The ability to do work or move objects Energy is all around you! – You can hear energy as sound. – You can see.
Unit 7 Energy. Energy is the ability to do work or cause change. I can work…but I won’t.
What is Energy? Forms of Energy
Potential & Kinetic Energy. Energy The ability to do work The ability to cause matter to move The ability to cause matter to change Measured in joules.
Forms and Transformations
Potential and Kinetic Energy Energy! All objects need energy to move! unit is Joules (J) Objects must store energy to be able to move later You store.
Energy, Work, and Power notes
Energy Study Guide for Review General Science. 1. Energy in the form of motion is ______ energy. kinetic.
Types of Energy Sections What is energy? Energy is the ability to do work Like work, energy is measured in joules (J) What are some examples.
Conservation of Energy. The Law of Conservation of Energy Energy cannot be CREATED or DESTROYED. Energy is just CONVERTED from one form to another.
Physics Energy. Law of Conservation of Energy energy cannot be created or destroyed only transferred from one form to another Electric LightChemical.
