Physical Science “Energy” Amplitude The maximum distance a wave vibrates Click here to reveal the definition! up or down from equilibrium. Angle of Incidence The angle an outgoing wave of light Click here to reveal the definition! makes with the normal. Angle of Reflection The angle an outgoing wave of light Click here to reveal the definition! makes with the normal. Chemical Energy The energy bound up in bonds Click here to reveal the definition! between atoms in molecules. Compression The moment when the particles in a Click here to reveal the definition! wave push together. Compressional Wave A wave in which the vibrations move parallel Click here to the to reveal direction theindefinition! which the wave moves. Conduction A form of heat transfer that involves Click here to reveal the definition! direct contact. Conservation of Energy A scientific law that states that energy is neither Click here created to reveal nor destroyed the definition! in any system but simply changes form. Convection The movement of fluid masses from areas of highhere density low density due to Click to by reveal the definition! temperature or salinity differences. Crest ClickThe here high to reveal point of thea definition! wave. Current Electricity Electrons flowing from a source of Click electrons here to through reveal athe conducting definition! medium such as metal wire. Electrical Energy The movement of electrons from one place Clicktohere another, to reveal either the indefinition! the form of static electricity or current electricity. Electromagnetic Spectrum The range of electromagnetic radiation, Click here to reveal the definition! from radio waves to gamma rays. Electromagnetic Wave A wave that does not need a medium Click here to reveal the definition! in which to travel. Energy Anything that has the ability to cause a change in the universe, as a change the position, Click heresuch to reveal theindefinition! speed, direction, or temperature of an object. Equilibrium Point The fixed position about which a wave Click here to reveal the definition! oscillates in a repeating pattern. Frequency The number of waves passing a point in Click a specific hereperiod to reveal of time, the definition! usually per second. Heat Energy The average energy of motion of Click here to reveal the definition! atoms and molecules. Joule The unit of measuring work; Click here to reveal the definition! 1J=1N x 1m Kinetic Energy The energy of moving atoms, particles, Click here to reveal the definition! or objects. Mechanical Energy The Clickenergy here to ofreveal large moving the definition! object. Normal An imaginary line perpendicular to the Click here to reveal the definition! surface of a reflecting surface. Nuclear Energy The energy released when the nuclei of Click here to reveal the definition! atoms are split or fused. Parallel Circuit An electrical circuit with at least two paths Click here to reveal the definition! through which the current can flow. Potential Energy Stored energy that can be used to do Click here to reveal the definition! work. Power A change in energy or the performance Click here to reveal the definition! of work over time. Radiation The movement of heat energy through electromagnetic Click here to reveal radiation the definition! (infrared, visible light, ultraviolet, and so on) Rarefaction The moment when the particles of a Click here to reveal the definition! wave pull apart. Resistor An object that turns current electricity into Clickanother here toform reveal of the energy, definition! such as heat, light, or sound. Series Circuit An electrical circuit with only a single Click here to reveal the definition! path for the current. Simple Machine A device such as the lever, inclined plane, or pulley, requires only application Clickwhich here to reveal thethe definition! of a single force to work. Static Electricity A positive or negative electrical charge on an object, of causing attraction, Click herecapable to reveal the definition! repulsion, or an electrical spark. Transverse Wave A wave that oscillates perpendicular to Click here to reveal the definition! the direction of travel. Trough ClickThe herelow to point revealof the a wave. definition!

Wavelength The smallest distance between identical parts a continuous wave; for example, Clickofhere to reveal the definition! the distance between consecutive crests. Work The distance an object moves Click here to reveal the definition! multiplied by the force that moves it.
