FLASHCARD QUESTION
Front
What is centripetal force?
Back
Centripetal force is the net force that acts on an object moving in a circular path, directed towards the center of the circle.

FLASHCARD QUESTION
Front
What is the formula for centripetal acceleration?
Back
Centripetal acceleration (a_c) is given by the formula a_c = v^2 / r, where v is the tangential velocity and r is the radius of the circular path.

FLASHCARD QUESTION
Front
What is the relationship between period and frequency in circular motion?
Back
The period (T) is the time taken for one complete revolution, while frequency (f) is the number of revolutions per unit time. They are related by the formula f = 1/T.

FLASHCARD QUESTION
Front
What is tangential velocity?
Back
Tangential velocity is the linear speed of an object moving along the circular path, measured at any point along the path.
6.
FLASHCARD QUESTION
Front
What happens to centripetal force if the speed of an object in circular motion increases?
Back
If the speed of an object increases, the centripetal force must also increase to maintain the circular motion, as it is proportional to the square of the speed.

FLASHCARD QUESTION
Front
What is the direction of centripetal acceleration?
Back
Centripetal acceleration always points towards the center of the circular path.
