An object in motion remains in motion at a constant velocity unless acted on by an unbalanced force.
Newtons 1st law
Forms of energy
Mechanical, chemical, nuclear, solar, thermal, electical, and sound
Is the energy of motion
Kinetic energy
all waves must have what to travel
energy
all matter is composed of _____ and _______ particles
positive and negative
Newton's 1st law is often called
Law of inertia
energy an object has due to its motion or position
Mechanical energy
particles packed tightly together and only vibrate
solid
this requires a medium in order to transport their energy
mechanical waves
the flow of charged particles is a
electric current
States that the net force is equal to the acceleration times the mass of the object
Energy caused by chemical reactions.
chemical energy
particles loosely packed and can slide past one another
liquid
medium moves in a direction perpendicular to the direction that the wave moves
transverse wave
control the movement of electric current by providing paths for electrons to follow
circuits
states that for every action, there is an equal and opposite reaction
Newton's 3rd law
energy released when the nuclei of atoms are split or fused
nuclear energy
particles move freely in all directions except during occasional collisions
gas
top of the wave
crest
objects become positively charged when they lose electrons and negatively charged when they gain electrons
electric charge
formula for momentum is
Mass times velocity(p=mv)
the suns rays that reach the earth
plasma
line drawn through the center of the wave
rest position
faster moving electric charges
higher current
