Engineering Spring 2012 Welcome Copyright © 2012 Little Engineers of Florida
Engineering Spring 2012 Copyright © 2012 Little Engineers of Florida F = m a Work = force * distance Energy = force * distance Potential Energy = m *g * h Kinetic Energy = ½ m v 2
Engineering Spring 2012 Copyright © 2012 Little Engineers of Florida PE = mgh KE = ½ m v 2 Conservation of Energy PE = mgh = ½ m v 2 = KE
Engineering Spring 2012 Copyright © 2012 Little Engineers of Florida PE = mgh KE = ½ m v 2 S = S 0 + V 0 t + ½ a t m/s 2 = 5m m * 9.8 * 5 = ½ m v * 5 = ½ v 2 v = SQRT (2 * 9.8 * 5) v = m/s
Engineering Spring 2012 Copyright © 2012 Little Engineers of Florida weight = m*g *(r/s) 2 r = radius of earth s = distance above earth Energy = m*g *(r/s) 2 * ds
Engineering Spring 2012 Copyright © 2012 Little Engineers of Florida weight = m*g *(r/s) 2 r = radius of earth s = distance above earth Energy = m*g *(r/s) 2 * ds So Total Energy to get in space, PE in space = g * m * r PE = KE g * m * r = ½ m v 2 S sound = 340 m/s, EV = 33 * S sound
Unit 7 Energy. Energy is the ability to do work or cause change. I can work…but I won’t.
EPE – Calories- Law of Conservation of Energy and Work-Energy Theorem.
Lecture 1: Energy Reading: Zumdahl 9.1 Outline –Energy: Kinetic and Potential –System vs. Surroundings –Heat, Work, and Energy.
Oscillations and Waves Energy Changes During Simple Harmonic Motion.
Physics 11 Advanced Mr. Jean April 23 rd, The plan: Video clip of the day Return Quiz Review Quiz Check homework problems Conservation of energy.
Principles of Physics. Objects have energy if they are able to do things A way of explaining why things happen Energy is a scalar quantity (no direction)
Energy. A Few Types of Energy 1. Mechanical 2. Chemical 3. Thermal (Heat) 4. Solar 5. Electrical 6. Nuclear 7. Sound 8. Light.
How is Work and Power Related? Chapter 5 Work and Power Goals: define and calculate work, energy, kinetic energy, potential energy, power and use the concept.
Escape velocity The condition for escape is to have KE > U Far from earth, g decreases so U = mgh.
Work, Energy and Power. Is the student doing work in pushing against the wall?
The ability to do work Work = Force x distance.
Energy can change from one form to another without a net loss or gain.
UNIT 4 Work, Energy, and Power. How does the work required to stretch a spring 2 cm compare with the work required to stretch it 1 cm? 1) same amount.
TRASKET BALL FEATURING THE BRIGHT STUDENTS OF MS. WILLIAMS.
Work and Energy Dr. Robert MacKay Clark College. Introduction What is Energy? What are some of the different forms of energy? Energy = $$$
Mr. Jean November 21 st, 2013 IB Physics 11 IB Physics 11.
Work and Energy Physics 100 Chapt 5. Physicists definition of work dist Work = F x dist A scalar (not a vector) dist.
9: Motion in Fields 9.4 Orbital Motion. Orbital Motion Keplers Third Law: This law relates the time period T of a planets orbit (its year) to the distance.
ENERGY What is Energy? Ability to do WORK Measured in Joules (calories or kilocalories)
Review for Energy, Work, Power Test. Work is always done ? What is the definition of work? A force moves an object in the direction of the force.
HW Duep. 672 #1-7 – turn it in!!! HW tonightWorksheet on your way out the door – worth 11 pts, 1 pt per problem Do Now Take a study guide & clicker LOOK.
Physics Energy. Law of Conservation of Energy energy cannot be created or destroyed only transferred from one form to another Electric LightChemical.
Forms of Energy & Energy Conversions. Forms of Energy Mechanical Energy: Related to motion of objects –Ex : moving machine parts Windmill Engine piston.
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?
Chapter IV Work and Energy A. Work Done by a Constant Force B. The Work-Energy Theorem C. Work Done by a Varying Force or on Curved Path D. Power E. Gravitational.
