Angular Momentum Flashcards
How do you calculate angular momentum?
Angular momentum possessed by a body is equal to the product of its moment of inertia and its angular velocity.
H = Iω
TRUE or FALSE: Each segment of the body has its own momentum?
TRUE
Hs = (Is)(ωs/Gs) + (ms)(r^2)(ωGs/G)
TRUE or FALSE: Angular momentum can be changed mid flight.
FALSE, momentum cannot be changed mid fight
Define momentum
Momentum is the quantity of motion that an object has.
How can an individual change angular velocity, despite not being able to change angular momentum?
An individual can influence moment of inertia which will change angular velocity.
If moment of inertia increases, angular velocity MUST decrease.
What is the relationship between angular acceleration, net moment, and moment of inertia?
Angular acceleration is directly proportional to net moment and inversely proportional to moment of inertia.
TRUE of FALSE: if a one body in a closed system looses angular momentum, another must gain angular momentum.
TRUE, momentum is always conserved, whether angular or linear.
