Q-vectors can be determined wholly with: geopotential height and temperature on a constant pressure surface.Q-vectors always point in the direction of ascending air. For an idealized cyclone and anticyclone in the Northern Hemisphere (where <), cyclones have Q-vectors which point parallel to the thermal wind and anticyclones have Q-vectors that point antiparallel to the thermal wind
For this reason, the in-line slider-crank mechanism produces balanced motion. This balanced motion implies other ideas as well. Assuming the crank arm is driven at a constant velocity, the time it takes to perform a forward stroke is equal to the time it takes to act a reverse stroke. The crank moves in only one direction, provided the position ...

The omega equation is a culminating result in synoptic-scale meteorology.It is an elliptic partial differential equation, named because its left-hand side produces an estimate of vertical velocity, customarily [1] expressed by symbol , in a pressure coordinate measuring height the atmosphere.
While geostrophic motion refers to the wind that would result from an exact balance between the Coriolis force and horizontal pressure-gradient forces, [1] quasi-geostrophic (QG) motion refers to flows where the Coriolis force and pressure gradient forces are almost in balance, but with inertia also having an effect.

In an inertial frame of reference (subscripted "in"), Euler's second law states that the time derivative of the angular momentum L equals the applied torque: = For point particles such that the internal forces are central forces, this may be derived using Newton's second law.

The tautochrone problem is a special case of Abel's mechanical problem when () is a constant. Abel's solution begins with the principle of conservation of energy – since the particle is frictionless, and thus loses no energy to heat , its kinetic energy at any point is exactly equal to the difference in gravitational potential energy from its ...
