Flash Cards for Circular Motion
Cards in this deck (10)
- 1What is 'One Radian'?One Radian is the angle subtended by an arc of length equal to the radius of the circle
θ (In radian) = Arch length / Radius
θ = s / r - 2What is the Right Hand rule?Imagine holding the axis of rotation of a rotating body with your right hand such that the curled fingers will represent the rotating motion of the body while the outstretched thumb will represent the direction of Angular Displacement.
- 3What is Angular Velocity?It is defined as the time rate of change of limiting angular displacement [ω (vector quantity)]
- 4What is Angular Acceleration?The average angular Acceleration is defined as the time rate of change of angular velocity [α (vector quantity)]
- 5What is UCM?UCM can be defined as the periodic motion of a particle moving along the circumference of a circle with a constant speed.
- 6What is a period of UCM?It is defined as the time taken by a particle performing UCM to complete one revolution is called as a periodic time or period (T)
- 7What is Frequency (n) of UCM?It is the number of revolutions performed by a particle performing UCM in unit time (T)
- 8What is Centrifugal Force?It is defined as a pseudo force in UCM which acts along the radius and directed away from the center of the circle.
- 9What is Banking of road? And what is angle of banking?The Process of raising of the outer edge of the road over its inner edge through certain angle is known as banking of road. And the angle made by the surface of the road with horizontal surface of road is called angle of banking.
- 10What is Conical Pendulum?Conical pendulum is a simple pendulum, which is given such a motion that the Bob describes a horizontal circle and the string describes a cone.
