1 Energy Animation Examples of Kinetic and Potential Energy

2 Roller Coaster  Energy is conserved throughout the ride and is merely being changed from K.E. to P.E. and vice versa  Notice that the Total Mechanical Energy remains constant during the animation

3 Pendulum Example  At the highest point on each side, the Kinetic Energy is equal to zero  The Energy is being converted back and forth from K.E. to P.E.

4 Section 5-3 Conservation of energy

5 Conserved Quantities  The mass of the light bulb is constant  This is true if the light bulb is whole or in pieces  We will be applying this same principle to energy

6 Mechanical Energy  Definition: the sum of kinetic energy and all forms of potential energy  ME= KE + ∑PE  Mechanical energy is often conserved

7 Energy Classification Energy Mechanical KineticPotential Elastic Gravitational Nonmechanical Nuclear, Chemical, Electrical

8 Conservation of Mechanical Energy  In the absence of friction, the total mechanical energy remains the same  This is called the conservation of mechanical energy  ME i = ME f  Initial mechanical energy = Final mechanical energy

9 ME cont.  Energy conservation occurs even when acceleration varies  Example: The Roller Coaster Animation  Exception to the rule: Mechanical energy is not conserved in the presence of friction  Sanding block in Figure 5-12
