2.1.5. Thermal

2.2. Potential

2.2.1. Mechanical

2.2.2. Chemical

2.2.3. Gravitational

2.2.4. Nuclear

3. Definition

3.1. The ability to do work

5. Potential Energy

5.1. Stored Energy

5.1.1. Bonds of Atoms

5.1.1.1. Examples:

5.1.1.1.1. Atoms in wood that allow it to burn

5.1.1.1.2. Energy in the nucleus of atoms

5.1.1.1.3. Nutrients/atomic bonds in food (like glucose)

5.1.2. Position of parts

5.1.2.1. Examples:

5.1.2.1.1. Compressed spring

5.1.2.1.2. Gravity pulling something high, downwards

5.2. Factors of PE in a system:

5.2.1. Height/distance and mass

5.2.1.1. Gravitational PE = m • g • h

5.3. Distance affects the transfer of energy as such: When there is more distance, more energy dissipates into thermal energy in the air, as more is lost during the time it took to transfer. This means that there is less energy transferred the more distance there is.

5.4. Forces already existing in objects that will be overcome using energy:

5.4.1. Friction

5.4.1.1. Static

5.4.1.2. Air resistance

5.4.1.3. Sliding

5.4.1.4. Rolling

5.4.2. Gravitational force
