FLASHCARD QUESTION
Front
What is centripetal acceleration?
Back
Centripetal acceleration is the acceleration directed towards the center of a circular path, which keeps an object moving in that circular path.
2.
FLASHCARD QUESTION
Front
Why is centripetal acceleration present in circular motion?
Back
Centripetal acceleration is present in circular motion due to the change in direction of the object's velocity as it moves along the circular path.
3.
FLASHCARD QUESTION
Front
What is the formula for centripetal acceleration?
Back
The formula for centripetal acceleration (a_c) is a_c = v^2 / r, where v is the tangential speed and r is the radius of the circular path.

FLASHCARD QUESTION
Front
What does 'change in velocity' refer to in the context of circular motion?
Back
In circular motion, 'change in velocity' refers to the continuous change in the direction of the velocity vector, even if the speed remains constant.
5.
FLASHCARD QUESTION
Front
What is tangential velocity?
Back
Tangential velocity is the linear speed of an object moving along a circular path, measured at any point along the path.
6.
FLASHCARD QUESTION
Front
How does tangential velocity relate to centripetal acceleration?
Back
Tangential velocity is used in the formula for centripetal acceleration; as tangential velocity increases, centripetal acceleration increases if the radius remains constant.
7.
FLASHCARD QUESTION
Front
What is the relationship between radius and centripetal acceleration?
Back
Centripetal acceleration is inversely proportional to the radius; as the radius increases, the centripetal acceleration decreases for a constant tangential speed.
