The time of flight of a projectile on downward inclined plane depends upon angle of projection and angle of inclination of the plane.

Vector Quantities: Vector quantities refer to the physical quantities characterized by the presence of both magnitude as well as direction. For example, displacement, force, torque, momentum, acceleration, velocity, etc.
Angular displacement, Angular velocity and Angular acceleration all of these are vector quantities.
The motion of a particle round a fixed axis is circular.
In order to completely specify angular displacement by a vector, it must fix
* direction of the axis of rotation
* magnitude of angular displacement
* sense of angular displacement
