Common examples include constant forces, simple harmonic motion, and circular motion. Particular forces such as free fall and projectile motion, effects of electrical and magnetic forces, forces of thermal change, and surface forces such as frictional and viscous forces are also sometimes included. |

These include gravitational cases (Free fall, projectile motion, orbital motion), Thermal change, Electrical, magnetic, and material contact forces including surface (frictional), viscous, buoyant, and elastic forces. There are also chemical forces, which are derived from chemical action.
F:: force
m:: mass of particle
a:: acceleration (acceleration toward center)
F = m*a
F:: restoring force
x:: distance from equilibrium point
k:: force constant
F = - k*x
In uniform circular motion, where the centripetal acceleration (acceleration toward the center)
F:: centripetal force (force toward center)
m:: mass of particle
r:: radius of circle
v:: speed of motion
a:: centripetal acceleration (acceleration toward center)
F = m*a = m*v2/r

Connections to personal studies, anthropology, culture, institutions, sociology, and history will be developed as the site expands. |

Other areas of science including biology, earth science, astronomy, and chemistry may be used to illustrate this. Other areas of physics can be connected. The structure of matter, quantum physics, relativity, electronmagnetism, thermodynamics, and other aspects of emchanics can be connected. |
