circular motion Flashcards
time for 1 revolution
period
nukber of revolutions per second
frequency
instantaneous speed of object moving in a circular path
directed at a tangent to circular path
tangential speed
netforce that causes circular motion
centripetal force
acceleration caused by change in direction inward for an object miving in a curcular path
centripetal acceleration
tendency of an ibject to continue its state of motion
inertia
objects move in a circular path at a constant speed
uniform circular motion
formula for circumference
c = 2pir
in circular motion what is the direction of an objects velocity
at a given instant, tangent to circular path
what does tangent mean
touches curve at exactly one point
in curcular motion what is the direction of centripetal force
inward
what vector is tangent to the path of circular motion
velocity/speed
in curcukar motion what is the direction of centripetal acceleration
inward
describe a situation where centripetal force and acceleration are in opposite directions
none
name two vectors that are perpendicular to each othher
fc and v
