General physics

Electronvolt

Physics; General physics

A unit of measurement for energy on atomic levels. 1 eV = 1.6 x 10 -19 J.

Equilibrium

Physics; General physics

The state of a nonrotating object upon whom the net torque acting is zero.

A device made of two coils, which converts current of one voltage into current of another voltage. In a step-up transformer, the primary coil has fewer turns than the secondary, thus increasing the ...

Universal gas constant

Physics; General physics

Represented by R = 8.31 J/mol • K, the universal gas constant fits into the ideal gas law so as to relate temperature to the average kinetic energy of gas molecules.

Uncertainty principle

Physics; General physics

A principle derived by Werner Heisenberg in 1927 that tells us that we can never know both the position and the momentum of a particle at any given time.

Transverse waves

Physics; General physics

Waves in which the medium moves in the direction perpendicular to the propagation of the wave. Waves on a stretched string, water waves, and electromagnetic waves are all examples of transverse ...
