Newtonian world and astrophysics: Circular motion Flashcards
what are radians a unit of
Angle
what is the period of an oscillation in circular motion
The time for the object to rotate through 360 degrees
define angular velocity
the angle traveeled through per unit time
to keep a object moving at a constant speed what needs to be applied
a constant centripetal force
how does velocity act in reference to the centripetal force
the centripetal force is perpendicular to the velocity
what equation links linear and angular velocities?
v=ωr
is an object moving with circular motion always accelerating
yes, as direction is always changing, acceleration is always changing
what equation links acceleration and angular velocity
a=ω^2r
how is acceleration and velocity linked in circular motion
a=v^2/r
what equation links centripetal force and linerar velocity
F=mv^2/r
what equation links centripetal force and angular velocity
F=mω^2r
