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.
In UCM, what direction does centripetal acceleration point?
Towards the center of the circle.
In UCM, what direction does centripetal force point?
Towards the center of the circle.
In UCM, what direction is the velocity vector?
Tangent to the circle.
In a gravitational vector field diagram, what do the vectors represent?
The strength and direction of the gravitational force between two objects.
In a gravitational vector field diagram, where are distances calculated from?
Between the centers of mass of the objects.
In UCM, what is the direction of centripetal acceleration, centripetal force, and velocity?
Centripetal Acceleration: Towards the center | Centripetal Force: Towards the center | Velocity: Tangent to the circle
