QuEstion:

  • A particle moves in circle of radius 50m with a linear speed of 10m/s. The angular of velocity of the particle is?

AnswEr:

  • The angular velocity of particle is 0.2 rad/s.

SteP By SteP ExplainaTion:

  • {\mathfrak{Given}}\begin{cases}\sf{radius(r)=50\:m}\\ \ \sf{linear\:speed(v)=10ms^{-1}}\\ \ \sf{angular\: velocity(\omega)=?}\end{cases}

\underline{\mathfrak{To\:Find:}}

angular speed

As we know that linear velocity =

\sf{v=\omega r}\\ \\ \\ \longrightarrow \sf{\omega=\frac{v}{r}}

Now, putting the values;

\longrightarrow\sf{\omega=\frac{10}{50}}\\ \\ \\ \longrightarrow\sf{\omega=\frac{1\cancel{0}}{5\cancel{0}}}\\ \\ \\ \longrightarrow\bf{\omega=0.2\:rads^{-1}}

ConcePt:

  • Rate of change of angular displacement with time is known as Angular velocity.
  • It is a vector quantity.
  • Direction of angular velocity can be obtained from right hand rule.
  • Rate of change of angular velocity is known as angular acceleration.
