What is the effect of a net centripetal force?
It causes an object to move in a circular path.
What happens when the string breaks in a UCM setup?
The object will move in a straight line tangent to the circle at the point where the string broke.
What happens when the car moves at a constant speed around a circular track?
The car's acceleration is directed towards the center of the circle.
What happens when a satellite is orbiting the Earth in a circular path?
The gravitational force provides the centripetal force necessary for this motion.
What is the key difference between centripetal and centrifugal force?
Centripetal: Real force, center-seeking | Centrifugal: Apparent force, center-fleeing.
Compare the velocity and speed of an object in uniform circular motion.
Speed: Constant magnitude | Velocity: Changing direction, therefore not constant.
What are the differences between centripetal and centrifugal forces?
Centripetal: Center-seeking, real force causing circular motion | Centrifugal: Center-fleeing, apparent force felt in a rotating frame.
Compare speed and velocity in uniform circular motion.
Speed: Constant magnitude | Velocity: Changing direction, therefore not constant.
