1 Potential and kinetic energy 1
PE=mgh m=mass g=gravitational acceleration 9.8 m/s2 h=height Conversion from potential to kinetic energy KE=mv2/2 v=speed

2 Gravitational potential energy

3 Forms of potential energy
atomic E=mc2 mechanical chemical electrical

4 Forms of kinetic energy

5 Magnitude of energy 1 calorie = 4.18 joules

6 Energy and force Force = rate of change of momentum=mass x acceleration

7 Temperature K = C +273 F = C

8 Density & pressure Pressure = force / unit area =density x temperature
Density = mass / unit volume The ideal gas law :                                                            V = Volume; n = Number of moles; R = Universal gas constant; T = Absolute temperature; P = Absolute pressure

9 phases

10 Multiple phases

11 Temperature and heat Heat is flow of energy
Temperature is average kinetic energy heat

12 Heat & phase transition
Water holds more thermal Energy at lower temperature

13 density & energy

14 heat transport Conduction Convection Radiation

15 Mass transfer Diffusion, differentiation, & advection

16 Microscopic world

17 Atoms, proton, neutron, electron

18 Mass-energy Fission & Fusion

19 Atomic structure of hydrogen

20 Energy level of atoms

21 Fundamental forces of nature
