energy
what is kinetic energy?
kinetic energy is energy in an object possesses by virtue of its motion
what is JJ Thompson's contribution to the atomic theory
Thompson said that the atoms are a positive charge with negative particles embedded in it
what is newtons first law of motion
the first law is in the absence of force an object remains in its present state of motion - either at rest or moving at a constant speed in the same direction
what are acids
a compound is in an aqueous solution that neutralizes a base to form a salt and water
carbon
c
what is potential energy?
potential energy is energy that is stored and can be released by conversion into a different form of energy.
what is Demetrius' contribution to the atomic theory
Demetrius said that everything is made of tiny particles
the acceleration of an object is proportional to the force acting on it
what are bases
base is a compound in the aqueous solution that neutralizes acid to form a salt and water
oxygen
o
what is internal energy?
internal energy is the sum of all kinetic energies possessed by all the particles in a substance.
what is Bohr's contribution to the atomic theory
Bohrs said that the electrons orbit the nucleus
what is the third law of motion
the 3rd law of motion is when one object pushes on another with a certain force, the second object pushes back on the first one with = force
what happens when acids and bases are mixed
they mix together and produce salt and water
nitrogen
N
what type of energy comes from the sun?
visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
what is Chadwickscontribution to the atomic theory
Chadwick said discovered/proved the existence of the neutrons
what are the three laws of motion called
laws of inertia and acceleration

what are some drawbacks of using fossil fuels as a main source of energy?
polution, oil spill, and risk of having our energy scourses interupted by wars or nautral disaster.
