uniform circular motion Flashcards
What is uniform circular motion?
Motion in a circular path at a constant speed.
True or False: In uniform circular motion, the velocity of an object is constant.
False.
What is the direction of acceleration in uniform circular motion?
Towards the center of the circular path.
Fill in the blank: The term ‘centripetal acceleration’ refers to the acceleration directed ________ the center of the circular path.
towards
True or False: In uniform circular motion, the speed is changing.
False.
True or False: The net force acting on an object in uniform circular motion is directed tangentially to the path.
False.
What is the net force required to keep an object in uniform circular motion called?
Centripetal force.
In the context of uniform circular motion, what does ‘m’ represent?
The mass of the object in motion.
True or False: Centripetal force can be provided by friction, tension, or gravity.
True.
What happens to the centripetal acceleration if the speed of the object is doubled?
It increases by a factor of four.
What is the effect of increasing the radius on the centripetal acceleration if the speed remains constant?
Centripetal acceleration decreases.
True or False: An object moving in uniform circular motion experiences a net force acting on it.
True.
What type of path does an object in uniform circular motion follow?
A circular path.
What is the relationship between frequency and period in uniform circular motion?
Frequency (f) is the reciprocal of period (T): f = 1/T.
What unit is frequency measured in?
Hertz (Hz).
