An aircraft executes a horizontal loop of radius $1.00\; km$ with a steady speed of $900 \;km/h$. Compare its centripetal acceleration with the acceleration due to gravity.
In uniform circular motion, the velocity vector and acceleration vector are
A particle is in uniform circular motion, then its velocity is perpendicular to
If the frequency of an object in uniform circular motion is doubled, its acceleration becomes
The net applied force on a body in uniform circular motion should always be
