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.
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 unit to measure work is ___________ The two requirements: Example: How much work is done if the guy pushes with 40 N to move the 20 N box.
Energy is Conserved. Page 220 Example 7.9 Gravitational Potential Energy = mgh = mgy Elastic Potential Energy = ½ky 2 F spring = ky Kinetic Energy = ½mv.
Chemical Energy Electrical Energy Potential Energy Kinetic Energy.
What is energy?. Forms of Energy: KE = Kinetic Energy (motion) PE = Potential Energy (position) ME = Mechanical Energy = KE + PE = ½ mv 2 + mgh.
Energy – the ability to do work W = Fd = m a d V f 2 = V i 2 + 2a x V f 2 - V i 2 = + 2a x V f 2 - V i 2 = a x 2.
