Circular motion
Cards in this deck (11)
- 1relation between angular parameters and linear parameters1) s=r(theta)
2) v=r(omega)
3) a=r(alpha) - 2Right hand thumb ruleimagine the axis of rotation to be held in right hand with the fingers curled around it and thumb outstretched,
1) curled fingers give the direction of motion
2) the direction of outstretched thumb gives the direction of angular displacement vector - 3relation between angular acceleration and linear accelerationa=✓[(a_t)^2+(a_r)^2]
- 4what is centrifugal forceis pseudo force which acts radially outward
- 5what is banking of roadprocess of raising outer edge of road over its inner edge through certain angle is known as banking of road
- 6what is centripetal forcea real force acting radially inward
- 7maximum velocity with which vehicle can safely driven around curved horizontal Roadv=✓(u)rg
- 8maximum velocity with which vehicle can safely travel along banked Roadv=✓rgtan(theta)
- 9period of conical pendulumT=2π✓(r/gtan(theta))
- 10velocity of Bob in conical pendulumv=✓rgtan(theta)
- 11why in non uniform circular motion radial acceleration is not constantspeed of particle has different values and different position
