Physics Paper 1- Circular Motion

• How do you convert degree to radians?

  2Pi/360
• Define Angular velocity

  The rate of change of an angle traveled
• What is the force required to keep an object moving in a circle at constant speed?

  Constant centripetal force
• What angle is the velocity of an object and centripetal force ?

  Perpendicular
• Why is an object moving in a circle always accelerating while at a constant speed?

  The direction is always changing
