MSJ Edition 3 QRT Ch. 6 11, 14, 16, 21, 30, 38, 39 To number 14 add: How many liters of water can be heated from 20 to 90 o C by the energy that falls on the roof in 8 hours? 4 What is energy? A) A mysterious thing that no one really understands. B) A fundamental component of the universe. C) A way to keep track of the ability to do work. D) All of the above. 3 5 What is energy? A) a mysterious thing that no one understands Richard Feynman, Lectures on Physics , Vol. 1, p. 4-1. B) a fundamental component of the universe Einstein E = mc 2 (mass can be converted to energy) But m = E/c 2 says mass comes from energy! C) keeps track of the ability to do work W = force x distance = mass x acceleration x distance E = W = f x d = m x a x d kg m/s 2 m kg m 2 /s 2 Joule, J What are the units of energy? 6 Categories or Types of Energy Mass energy Is the energy associated with the mass of an object. E = mc 2 Kinetic energy Is the energy associated with the motion of an object. E k = mv 2 Potential energy Is the energy associated with the position of an object when a force is acting on it. Equations depend on the origin of the force. 4 7 Forms of Energy Labels for different situations involving energy. Mechanical kinetic energy of a moving macroscopic object (like you walking, or a wheel spinning)....
