FLASHCARD QUESTION
Front
What is the formula to calculate frequency from rotations per minute (rpm)?
Back
Frequency (Hz) = Rotations per minute (rpm) / 60
2.
FLASHCARD QUESTION
Front
How do you convert frequency in Hz to angular velocity in radians per second?
Back
Angular velocity (rad/s) = Frequency (Hz) × 2π
3.
FLASHCARD QUESTION
Front
What is the relationship between tangential velocity and radius in circular motion?
Back
Tangential velocity (v) = Radius (r) × Angular velocity (ω) where ω is in rad/s.
4.
FLASHCARD QUESTION
Front
What is centripetal acceleration and how is it calculated?
Back
Centripetal acceleration (a_c) = v² / r, where v is tangential velocity and r is the radius.
5.
FLASHCARD QUESTION
Front
How do you calculate the tangential velocity of an object in circular motion?
Back
Tangential velocity (v) = 2πr / T, where r is the radius and T is the period of rotation.
6.
FLASHCARD QUESTION
Front
What is the definition of angular velocity?
Back
Angular velocity (ω) is the rate of change of angular displacement and is measured in radians per second.
7.
FLASHCARD QUESTION
Front
How is centripetal acceleration related to frequency?
Back
Centripetal acceleration (a_c) can be expressed as a_c = (2πf)²r, where f is frequency and r is the radius.
