(mechanics) A mechanism that translates a continuous rotation into an intermittent rotary motion, using an intermittent gear where the drive wheel has a pin that reaches into a slot of the driven wheel and thereby advances it by one step, and having a raised circular blocking disc that locks the driven wheel in position between steps.

(physics) The sum of the potential energy and kinetic energy of a body or system

The branch of mechanics dealing with the effects of stress and strain on physical bodies over time.

(medicine) A form of physiotherapy used to correct body posture and movement.

(physics) The branch of fluid mechanics that deals with the action of forces on gases.

(physics) The original formulation of quantum mechanics in which the operators were represented by time-dependent matrices.

(mathematics, physics) The application of calculus to classical mechanics.

(chemistry) A non-rigorous method of computing the structures, energies, and some properties of molecules by assuming they behave like small balls connected by springs.

(physics) The mechanics of objects moving at velocities considerably less than the speed of light.

(physics) classical or Newtonian mechanics rather than quantum mechanics.
