Circular Motion Flashcards
What is the definition of circular motion?
Circular motion is the movement of an object in a circular path.
True or False: In circular motion, the object’s velocity is constant.
False
What is the formula for centripetal acceleration?
a = v^2 / r
What is the direction of centripetal acceleration in circular motion?
Towards the center of the circle
What force is responsible for keeping an object in circular motion?
Centripetal force
What is the formula for centripetal force?
Fc = m * v^2 / r
What happens to centripetal force if the radius of the circle decreases?
Centripetal force increases
What is the relationship between centripetal force and mass in circular motion?
Directly proportional
What is the relationship between centripetal force and velocity in circular motion?
Directly proportional
What is the formula for angular velocity?
ω = v / r
