A back-and-forth movement about an equilibrium position. Springs, pendulums, and other oscillators experience harmonic motion.

Pascals

Physics; General physics

The unit for measuring pressure. One Pascal is equal to one Newton per metre squared, 1 Pa = 1 N/m 2 .

Node

Physics; General physics

The points on a standing wave where total destructive interference causes the medium to remain fixed at its equilibrium position.

Reflect

Physics; General physics

A wave on a string that is tied to a pole at one end will reflect back toward its source, producing a wave that is the mirror-image of the original and which travels in the opposite direction.

There are a few versions of this law. One is that heat flows spontaneously from hot to cold, but not in the reverse direction. Another is that there is no such thing as a 100% efficient heat engine. ...

Right-hand rule

Physics; General physics

A means of defining the direction of the cross product vector. To define the direction of the vector ( A × B ), position your right hand so that your fingers point in the direction of A , and ...

Rutherford nuclear model

Physics; General physics

The model of the atom according to which negatively charged electrons orbit a positively charged nucleus. This model was developed by Ernest Rutherford in light of the results from his gold foil ...
