Ability to do work and change matter Energy
SI unit for measuring energy Joule
3 main forms of energy kinetic, potential, radiant
form of energy involving the whole object moving kinetic
form of energy involving the forces acting upon an object potential
form of energy involving visible light and electromagnetic radiation radiant
energy from motion or forces that affect the whole object mechanical
energy from the motion and forces that affect atoms and molecules nonmechanical
law that states that energy and matter can neither be created nor destroy only transferred law of conservation of matter and energy
Formula for Kinetic Energy KE= 1/2 mv(square)
KE that refers to the entire object moving whole-body KE
KE that refers to the object not moving but changing positions Translational KE
KE that refers to spinning around an internal axis Rotational KE
True/False: Rotational motion is the same as circular motion False (Is NOT the same as)
What 2 factors increase rotational KE Increasing mass or speed
What 2 things can affect an objects rotational KE Size and Shape of an object
Deals with the individual molecules that are in constant motion Kinetic Energy of matter
energy formed from random motion in molecules thermal energy
energy caused by disturbances moving through a substance wave energy
