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)
