Bowling Ball Pendulum Warm Up Predict what will happen when the bowling ball is released from the tip of the teachers chin and then returns.

Bowling Ball Pendulum Warm Up Did the bowling ball smack the teacher in the chin? Did it rise higher or lower than its original height? At what point did the bowling ball have the most gravitational potential energy? At what point did the bowling ball have the most kinetic energy? How do we know this?

Transfer of Energy Energy Transfer: Energy transfer is the transfer of energy from one object or material to another. Energy Transformation: Energy transformation is the process of changing one form of energy to another.

Watch Music Video: Ok Go – “This Too Shall Pass” Make a list of all energy transfers you can find.

Share two energy transfers/transformations with your partner. Be ready to share with the class

Conservation of Energy Conservation of Energy is a fundamental principle that energy cannot be created or destroyed. Energy is just transferred between objects and transformed in to different forms.

Energy Review 1.What does energy allow us to do? 2.Is energy a physical object? 3.Can objects have energy? Why?

Energy Types Reminder Gravitational Potential Energy Kinetic Energy Elastic Energy Thermal Energy

Energy Cubes Activity: Track the energy transfers and transformations. Show the relationship between gravitational, kinetic, elastic, and thermal energies. Describe energy transfers and transformations between two time points in a scenario.

Energy Bar Charts (LOL) A visual way to account for the energy in a system. Where the energy is being stored and any transfers, into or out of the system Energy Conservation Equation:

Example 1 Draw an energy bar chart for a ball dropped. Initial point: Ball held above the surface Final point: Ball right before it hits the ground Energy Conservation Equation:
