Energy & Calc Motion

Unit 4: Energy / Calculating Motion

acceleration the rate at which speed changes
average speed total distance traveled divided by total time traveled
chemical energy the energy stored in chemical bonds
constant speed speed is not increasing or decreasing and there is no change in direction
electrical energy the energy of moving electrons
energy the ability to do work; measured in Joules
instantaneous speed the speed of an object at a given point in time
Law of Conservation of Energy states that energy can not be created or destroyed, only transferred
mechanical energy sum of the potential and kinetic energy of a system; energy of motion
nuclear energy energy associated with changes in the nucleus of an atom
radiant energy energy carried by an electromagnetic wave
speed distance an object travels per unit of time
thermal energy sum of the kinetic and potential energy of the particles in an object
velocity the speed and direction of a moving object
