5.2 circular motion

Cards (10)

  • what is 360 degrees in radians?
  • what are the components of this equation?
    ω = angular velocity
    T = time period
  • what is the relationship between time period and frequency?

    T = 1/ f
  • what is centripetal force? 

    a constant net force perpendicular to the velocity of an object that causes it to travel in a circular path
  • what do the components of this equation represent? 

    ω = angular velocity
    v = linear velocity
    r = radius
  • what happens to the angular velocity when the radius is doubled?
    stays the same
  • what happens to the radius when the linear velocity is doubled?
    radius is doubled
  • what factors effect centripetal acceleration?
    speed of the object
    radius of the circle
  • what is an experiment that investigates circular motion?
    • swing a bung around in a horizontal circle
    • suspended weight remains stationary as long as the centripetal force it supplies is enough to make the bung travel in a circular path
    • if centripetal force required is larger mass moves upwards
    • paper clip acts as a maker to make this clear
  • what are the components?
    A) bung
    B) glass tube
    C) paper clip
    D) string
    E) weight
