Centripetal acceleration
The acceleration of a body experiencing uniform circular motion. This acceleration is always directed toward the center of the circle.
Centripetal force
The force necessary to maintain a body in uniform circular motion. This force is always directed radially toward the center of the circle.
Chain reaction
The particles and energy released by the fission or fusion of one atom may trigger the fission or fusion of further atoms. In a chain reaction, fission or fusion is rapidly transferred to a large number of atoms, releasing tremendous amounts of energy.
Charles’s Law
For a gas held at constant pressure, temperature and volume are directly proportional.
Coefficient of kinetic friction
The coefficient of kinetic friction, , for two materials is the constant of proportionality between the normal force and the force of kinetic friction. It is always a number between zero and one.
Coefficient of linear expansion
A coefficient that tells how much a material will expand or contract lengthwise when it is heated or cooled.
Coefficient of static friction
The coefficient of static friction, for two materials is the constant of proportionality between the normal force and the maximum force of static friction. It is always a number between zero and one.
Coefficient of volume expansion
A coefficient that tells how much the volume of a solid will change when it is heated or cooled.
Coherent light
Light such that all of the associated waves have the same wavelength and are in phase.
