The combination of all forces acting on an object net force 44. forces acting on an object that combine and form a net force of zero bal- anced forces 45. Forces that produce a nonzero net force, which changes an object's motion unbalanced forces 46. (An object continues in uniform motion in a straight line/ at rest unless a resultant force acts.) The net force on an object is the cause of its acceleration Newton's First Law 47. The tendency to keep the same motion- remaining at rest or maintaining the same velocity Inertia 48. The acceleration of an object depends on the mass of the object and the amount of force applied. F=ma Newton's Second Law 49. For every action there is an equal and opposite reaction Newton's Third Law 50. The force that two surfaces exert on each other when they rub against each other Friction 51. The force of friction between two objects that are moving against each other kinetic friction 52. frictional force that prevents two surfaces from sliding past each 7 / 12 other - static friction 53. A force of attraction between objects that is due to their masses. Gravity 54. mass times velocity linear momentum 55. Momentum is conserved when two or more objects collide. Momentum may transfer but total momentum within the group stays the same Law of conservation of momentum 56. The ability of a material to bounce back after being disturbed Elasticity 57. Force exerted on an object that causes it to move Work 58. The ability to do work or cause change Energy 59. energy of motion kinetic energy 60. Energy that is stored and held in readiness potential energy 61. Force x distance Work formula 8 / 12 62. Joule (J) SI unit for work and energy 63. Energy stored by objects due to their position above Earth's surface. Increases with mass. gravitational potential energy 64. the energy stored in the chemical bonds of a substancechemical potential energy 65. Energy stored by something that can stretch or compresselastic potential energy 66. Energy carried by electromagnetic waves Electromagnetic energy (light energy) 67. The total energy of motion in the particles of a substance thermal energy 68. The rule that energy cannot be created or destroyed only transferred or converted Law of Conservation of Energy 69. the act or state of swinging back and forth with a steady, uninterrupted rhythm Oscillation 70. A state of balance to which an oscillating object eventually returns to after a disturbances is gone Equilibrium 71. waves that require a medium through which to travel mechanical waves 72. A wave that can transfer electric and magnetic energy through the vacuum of space Electromagnetic waves 9 / 12 73. A space where no particles of matter exist Vacuum 74. the oscillation is parallel to the direction the wave is traveling. longitudinal wave 75. Highest point of a wave Crest 76. Lowest point of a wave Trough 77. the maximum extent of a vibration or oscillation, measured from the position of equilibrium. The height of the wave. Amplitude 78. Horizontal distance between the crests or between the troughs of two adjacent waves Wavelength 79. The amount of time it takes one wavelength to pass a point Period 80. the number of complete wavelengths that pass a point in a given time - Frequency 81. Hertz (Hz) SI unit for frequency 10 / 12 82. electromagnetic waves that are visible to the human eye visible light 83. Red Color with longest wavelength and lowest energy 84. Violet Color with shortest wavelength and highest energy 85. Electromagnetic waves with the longest wavelengths and lowest frequencies and energy radio waves 86. Electromagnetic waves that have shorter wavelengths and higher frequencies and energy than radio waves. Microwaves 87. Third on the electromagnetic spectrum going from lowest to highest frequency. can be felt as heat infrared waves 88. Just shorter than visible violet light but longer than X-rays. Size of molecules ultraviolet 89. Wavelengths shorter than UV but longer than gamma X-ray 90. Electromagnetic waves with the shortest wavelengths and highest frequencies and energy gamma rays 91. The part of a longitudinal wave where the particles of the medium are close together. Compression 92. Particles pulled apart from each other expansion 93. How high or low a sound is Pitch 94. The greater the every of a wave the louder the sound Loudness 95. Longitudinal Type of wave sound is 11 / 12 96. Transverse Type of wave electromagnetic is 97. the oscillation is perpendicular to the direction the wave is traveling - transverse wave 98. Anything that has mass and takes up space Matter 99. Positive, nucleus Proton charge and location 100. neutral and nucleus neutron charge and location 101. Negative and outside nucleous Electron charge and location 102. electrons in the outermost energy level valence electrons 103. A pure substance made of only one kind of atom Element 104. the number of protons in the nucleus of an atom atomic number 12 / 12 105. A substance made up of atoms of two or more different elements joined by chemical bonds Compound 106. the attractive forces that hold atoms together chemical bonds 107. Compounds that contain carbon and hydrogen organic compound 108. A material that is composed of only one type of element or compound- pure substance 109. Combination of two or more pure substances Mixture 110. Any substance that has a definite composition Chemical 111. visible to the naked eye macroscopic 112. A group of atoms bonded together Molecule 113. a change of matter from one form to another without a change in chemical properties physical change 114. A change in the chemical composition that produces one or more new substances chemical change 115. When a chemical change occurs, atoms are rearranged and chemical bonds are broken or formed. chemical reaction 116. a substance that takes part in and undergoes change during a reaction.- Reactants 117. produced by an excess or shortage of electrons net electric charge 118. An atom or group of atoms that has a positive or negative charge. Ion
