What is the relationship between moment of inertia and angular velocity? The formula for moment of inertia is I=mxr^2. What is the relationship to angular velocity? During a pirouette, the rotational speed increases with a smaller moment of inertia…

Loading...I was able to easily calculate the average mass using the mean atomic mass. However, I do not understand how to calculate the nominal
hey, I need help with task 1 b) I can't get any further
Hello, I'm looking for a mathematical connection, or rather the formula, to solve the following problem. I'm currently studying for my thermodynamics exam and would need this information. Just the following demonstrative example: If I have a volume V1=3m^3 and a pressure p1 = 5 bar, then reduce the pressure to 2 bar, how much…
I need help writing a paper tomorrow can someone help me
When do you use the formula Eges=Epot+Ekin in physics and when do you use the formula Epot=Ekin for energy conversion?
Hello, can someone help me with my physics problem? That would be really nice (see picture).
Angular velocity x moment of inertia around the axis of rotation = angular momentum. This remains constant, excluding friction losses. During a pirouette, the dancer pulls her arms toward her, thus reducing her moment of inertia.
And if this becomes smaller, the angular velocity must increase so that the angular momentum remains constant!
Warum genau bleibt der Drehimpuls nochmal konstant?
Das Prinzip der Drehimpulserhaltung ist ein Naturgesetz.
Aus demselben Grund, wie ein bewegter Körper seine Geschwindigkeit und Richtung beibehält, solange keine äußeren Kräfte auf ihn wirken.
es gilt Drehimpulserhaltung.
