Schwankungen
fluctuations: In the 1920s, it was discovered that the current through a practical resistor actually has statistical fluctuations
(elektr.) Leitfähigkeit
conductance: The electrical conductance is the inverse of the resistance.
in Widerspruch zu etwas stehen
to contradict sth.: Modern developments in electromagnetic theory and circuit theory do not contradict Ohm's law when they are evaluated within the appropriate limits.
(relig.) Irrlehren
heresies: The German Minister of Education proclaimed that a professor who preached such heresies would be unworthy to teach science.
verkünden, behaupten
proclaim: The German Minister of Education proclaimed that a professor who preached such heresies would be unworthy to teach science.
Feindseligkeit
hostility: Critics reacted to his treatment of the subject with hostility when he first published his work.
Verbindung, Kontakt
junction: The voltage between the thermocouple terminals was proportional to the junction temperature.
Thermoelement
thermocouple: Later he used a thermocouple as this provided a more stable voltage source.
Volta-Säule
voltaic pile: For his experiments, he initially used voltaic piles (electrochemical cells).
Amperemeter (elektromech. Drehspulmesswerk)
galvanometer: The current flowing through a conductor can be measured by a galvanometer.
(elektr.) Widerstand
resistance: The reciprocal of the conductivity σ is the specific electrical resistance ρ (or resistivity).
el. Strom
current: The current flowing through a conductor can be measured by a galvanometer.
Kraft
force:
Now we can proceed as usual by plugging all horizontally directed forces into the horizontal form of Newton's second law.
unabhängig
independently:
It's often easier to analyze each direction independently.
vorgehen
proceed:
Now we can proceed as usual by plugging all horizontally directed forces into the horizontal form of Newton's second law.
Elektrische Ladung
eleictrical charge:
The unit of electrical charge is the coulomb.
resultierend
resultant:
The resultant force can be split up into the horizontal and vertical component.
Gleichung
equation:
The mass must me twice as large to satisfy the equation.
Schwebstoffe
suspended solid:
Salatschleuder
salad spinner:
Kettenkarussell
swing ride/swing carousel:
Trägheit
inertia:

sky of fixed stars:
Scheinkraft
fictional force:
Bezugssystem
frame of reference:
Inertialsystem
inertial frame of reference/inertial frame:
zentrale Anziehungskraft
central force:
ungenau
vague: Unfortunately this definition is a bit to vague to be useful.
umkreisen
to orbit: The moon orbits around the earth.
ausüben (z.B. eine Kraft)
to exert:
dahintreiben
to drift away: The astronaut lost his link to the space station and so he started to drift away.
ableiten, herleiten
to derive: You have to use mathematical equations to derive this law.
Erkenntnisse
perceptions: The perception, that forces always appear in pairs , is the central message of the Newton's Third Law.
kinderleicht
easy as ABC: With the now gained knowledge it is easy as ABC to solve the task.
Impulserhaltungssatz
conservation of momentum: The law "conservation of momentum" describes the momentum change of two objects in a collision.
Pleuelstange
connecting rod: The connecting rod connects the piston to the crankshaft in a engine.
Kurbelwelle
crankshaft: A crankshaft converts the linear motion of the pistons into rotational motion in a engine.
Verbrennungsmotor
internal combustion engine: An internal combustion engine is a machine with moving parts that uses a fuel to produce movement.
Kolben
piston: A piston is a part of an engine that moves up and down inside a cylinder and that causes other parts to move.
voreingestellt
preset: Compressors use a pressure switch to stop the motor when tank pressure reaches a preset limit.
