Physics Flashcards
Durchschnittsgeschwindigkeit
Average Velocity = Change in Position/time = Displacement/time
Kollinearer Vektor
Collinear Vector (Vectors that point in the same direction)
Verschiebung
Displacement (Smallest distance from where an object starts to where it ends up)
Momentangeschwindigkeit
Instantaneous speed (Speed at a moment in time)
Nicht kollinearer Vektor
Noncollinear vector (Vectors that are not on the same line (use Pythagorean theorem to add these types of vectors))
Skalare Größe
scalar quantity (Physical qunatity completely described by size)
Gleichförmige Geschwindigkeit
Uniform Velocity (An object is travelling at a constant speed along a straight line)
Vektormenge
Vector Quantity (Physical quantity described by size and direction)
Reibung
Friction (force that slows down or stops the movement of a sliding object)
Gravitationsfeldstärke
Gravitational Field intensity (The force of a unit mass at a point in the field)
Elastisch
Elastic (Energy from squishing or stretching something)
Elektrische Energie
Electrical energy (Energy from the movement of electrons)
Erdwärme
Geothermal (Energy from the ground)
Gravitativ
Gravitational (Energy due to the postition of an object compared to something else)
Kintetik
Kinetic (Energy due to movements of particles)
Nuklearenergie
Nuclear (Energy produced from nuclear reactions)
Strahlend
Radiant (Energy that travels by waves or particles such as heat or x-rays)
Amplitude
Amplitude (Height of a sound wave from baseline)
Verdünnung
Rarefaction (Part of the longitudanal waves there the particles are further apart)
Wellental
Trough (Valley or dip of a sound wave)
Frequenz
Frequency (How often the particles of the medium vibrate when a wav passes through it)
Tonhöhe
Pitch (The frequency of the sound)
Welleninterferenz
Interference of waves (When two or transverse waves pass through each other (constructive or destructive)^)
Diffraktion, Beugung
Diffraction (A change in direction of waves as they pass through a hole or some type of barrier)
Antinoden
Antinodes (Points that have maximum displacement)
Reflexion
Reflection (Waves reflect so the angle at which they go through the barrier equals the angle at which they come from the barrier)
Refraktion
Refraction (A change in direction of waves as they pass from one medium to another. Example: Water to air)
Longitudinalwellen
Longitudanal wave (A wave in which the medium vibrates parallel to the direction the wave is moving)
Transversalwellen
Transverse waves (A wave in which the medium vibrates perpendicular to the direction the wave is moving)
Universelle Wellenfunktion
Universal wave equation (Connects speed of wave to its frequency and wavelength)
Resonanz
Resonance (When one object vibrating at the same natural frequency of a second object causes the second object to vibrate to)
Kirchhoffsche Regeln
Kirchhoff’s laws for parallel circuits (Formulas illustrate relationship between voltage current and resistance)
Supraleiter
Superconductors (material that can conduct electricity (move electrons) from one atom to another with no resistance)
Ferromagnetismus
Ferromagnetism (some materials (iron) form permanent magnets or attract magnets)
Induktionsmagnet
Temporary magnet (These magnets only have their domains lined up while in the magnetic field produced by a permanent magnet or an electric current)
Elektromagnetismus
Electromagnetism (Ferromagnetic material (iron) that is inside coils of a wire and depend on electric current to make them magnetic)
Transformator
Transformer (Electrical device that moves electrical energy between two or more circuits using electromagnetic induction)
