- Curvilinear motion: This type of motion occurs when an object moves in a curved path.

- The velocity of a particle moving in a curved path is always tangential to the path moved. Hence, the tangential component of velocity is equal to velocity itself as the particle moves tangentially and the normal component is zero.

- The normal component is perpendicular to the velocity vector and passes through the centre of curvature. This type of co-ordinate system, in which motion of particle is described in two directions is known as normal and tangential co-ordinate system.

- R is the particle moving in a curved path shown in the diagram.

- Hence, Vnormal component = 0 and Vtangential component = velocity of the particle
