# Energy

### In our class we are going to use a precise, scientific definition of energy.

New Age Energy, an analysis

# Chemical potential energy

## Vibrational kinetic energy

### Atoms in a CH2 group, commonly found in organic compounds, vibrate in different ways:

Symmetrical
stretching
Asymmetrical
stretching
Scissoring (Bending)
Rocking Wagging Twisting

## Nuclear potential energy

### e.g. nuclear fusion.

Example of hydrogen atoms undergoing nuclear fusion.

# Animations: work and energy

• ### How High Will It Go?

HS-PS3-1. Use algebraic expressions and the principle of energy conservation to calculate the change in energy of one component of a system when the change in energy of the other component(s) of the system, as well as the total energy of the system including any energy entering or leaving the system, is known.

Disciplinary Core Idea Progression Matrix

PS3.A and 3.B:  The total energy within a physical system is conserved. Energy transfer within and between systems can be described and predicted in terms of energy associated with the motion or configuration of particles (objects)
