(24 cards)

elastic potential energy

Front

potential energy caused by restorative forces after an object is stretched, compressed, bent, sheared, or twisted

Back

potential energy = mass x strength of gravity x height (PE = mgh)

Front

equation for gravitational potential energy, where the value of g (strength of gravity at Earth's surface) = 9.81 m/second squared

Back

Hooke's law

Front

the strength of the restorative force is itself directly proportional to the amount of deformation; F = kx

Back

radiant energy

Front

the energy of electromagnetic radiation, visible light and other phenomena, (i.e.. radio waves, x-rays)

Back

potential energy

Front

energy associated with the forces acting upon an object

Back

chemical energy

Front

energy resulting from the chemical combination of atoms into molecules

Back

Kinetic energy

Front

energy of motion

Back

mechanical energy

Front

energy from motion or forces that affect a whole object

Back

electric potential energy

Front

electromagnetic potential energy caused by two stationary charged objects affecting each other

Back

magnetic potential energy

Front

electromagnetic potential energy caused by interacting magnetic fields

Back

joule

Front

SI unit of energy

Back

mechanics

Front

branch of physics that studies motion and forces

Back

whole-body kinetic energy

Front

simplest form of kinetic energy

Back

Energy = mass x (speed of light) squared

Front

Einstein's equation

Back

electromagnetic force

Front

the second strongest fundamental force; can either attract or repel; responsible for most known forces in the universe (except for the gravitational force & subatomic forces)

Back

strong nuclear force

Front

the strongest fundamental force, which binds subatomic particles together to form the nucleus of an atom

Back

translational motion

Front

motion in which an object moves in space, changing its position

Back

weak nuclear force

Front

the third-strongest fundamental force; affects certain subatomic particles; difficult to study

Back

electric potential energy, magnetic potential energy, chemical energy, elastic potential energy

Front

All result from the electromagnetic force

Back

gravitational force

Front

attractive force between all material objects; the weakest of the 4 forces

Back

the law of conservation of matter and energy

Front

matter and energy can neither be created nor destroyed but can only be converted from one form to another

Back

circular motion

Front

when an object changes its position along a circular path (the motion is centered on a point OUTSIDE the object), ie. the earth revolving around the sun

Back

rotational motion

Front

motion in which an object spins or rolls around an internal axis (ie. spinning baseball, rotating wheel); ie. the earth spinning on its axis

Back

mass, rotational speed, size, and shape

Front

factors that affect an object's rotational kinetic energy
