2. Uniform Circular Motion Flashcards
What does uniform mean in physics terms?
constant
What is uniform circular motion?
an object moving in a circular path with constant speed
What is acceleration doing during uniform circular motion?
changing the direction of the velocity to maintain the circular motion
For uniform circular motion, how are acceleration and velocity change related?
they have the same direction
What direction does ac face in uniform circular motion?
toward the center of the circle
What does centripetal mean?
toward the center
What is the equation for centripetal acceleration?
ac = (v2)/r
What is the magnitude if centripetal force?
F = (mv2)/r
What is tangential acceleration?
acceleration that changes an objects speed
