BJU Physical Science - Ch 6

The potential energy stored in the chemical bonds between atoms that is released or absorbed during chemical reactions. chemical energy
Law stating that the total amount of energy entering the process equals the total of all the forms of energy that exist at the end of the process. Also known as the first law of thermodynamics. conservation of energy
The ability to do work through the action of the electromagnetic force on and by electrical charges. electrical energy
The ability to do work. energy
The SI unit of energy; equal to 1 Newton-meter of work. joule
The energy of motion which depends only on the system’s mass and speed; a form of mechanical energy. kinetic energy
The energy equivalent to matter itself, according to the equation in Einstein’s special theory of relativity, E = mc2. mass energy
The ability of a magnetic field to do work on magnetic objects and on moving electrical charges. magnetic energy
The energy of a system due to its position or its motion. mechanical energy
The potential energy stored in an atom’s nucleus that is released or absorbed when an atom experiences nuclear fission or fusion. nuclear energy
The energy of a system due to its position or condition; a form of mechanical energy. potential energy
For a machine or process, the ratio of energy or work produced to the energy or work present beforehand; a measure of the effectiveness of the machine or process for converting energy from one form to another. efficiency
The transmission of energy through matter by the periodic motion of particles (mechanical waves). acoustic energy
The sum of the kinetic energies of all the particles in an object, directly proportional to the temperature of the object. thermal energy
The potential energy of a system due to its weight and its height above a zero reference height. gravitational potential energy
The combined action of electrical and magnetic energies in the form of wavelike, radiant energy. electromagnetic radiant energy
Law stating that energy and matter cannot be created or destroyed, only changed in form. first law of thermodynamics
A property of a moving system that is proportional to its speed and mass Momentum
In a system of colliding objects, the sum of their momentum a before the collision is equal to the sum of their momentums afterward if no external forces act on the objects. Conservation of momentum
