Elements
how many charges does a proton contain
1
This process occurs when two light atomic nuclei combine to form a single heavier one, releasing massive amounts of energy.
nuclear fusion
Often called the Law of Inertia, this law states that an object at rest will stay at rest unless acted upon by an outside force.
Newton's First Law of Motion
In physics, work is calculated by multiplying force times this variable
distance
This is the highest point of a transverse wave
crest
how did Henry Mousley arrange each element on the periodic table in order
This is the splitting of a heavy atomic nucleus into two lighter nuclei, which is the process used in modern nuclear power plants.
nuclear fission
what fruit dropped on Newtons head
Apple
Named after an English physicist, this is the standard SI unit used to measure both work and energy
Joule
This is the lowest point or valley of a transverse wave
Trough
what does Na stand for in the periodic table?
Sodium
Consisting of two protons and two neutrons, this type of radioactive particle is actually just a helium nucleus.
alpha particle
This law is summarized by a famous three-variable equation proving that heavier objects require more force to accelerate.
Newton's Second Law of Motion
If you push a heavy brick wall for an hour but the wall does not move, this is the total amount of work done
zero
This measurement describes the distance from one crest to the very next crest.
wavelength
These are the specific electrons located in the outermost shell of an atom that determine how it bonds with others.
valence electrons
This term describes the self-sustaining series of fission events where neutrons released by one reaction trigger further reactions.
chain reaction
This is the property of matter that resists changes in motion, which increases directly with an object's mass.
Inertia
This term describes the rate at which work is done, typically measured in Watts.
Power
Measured in Hertz, this term describes the number of wave crests that pass a fixed point per second.
frequency
The horizontal rows on the periodic table are called periods, while the vertical columns are called this.
groups/families
This is the time required for one-half of the atoms of a radioactive substance to decay into another element.
half-life
This law states that for every action, there is an equal and opposite reaction.
This is the percentage of input work that a machine converts into useful output work, which is never 100% due to friction.
efficiency
This is the maximum distance a wave vibrates from its rest position, which dictates the volume of a sound wave.
