The direction of the momentum vector is the same as the direction of the velocity of the ball. In a previous unit, it was said that the direction of the velocity vector is the same as the direction that an object is moving.

So that means the angular velocity and the angular momentum both point downward on the other hand if the object is rotating in the counterclockwise.

Therefore, the direction of the angular momentum vector in orbital motion is perpendicular to the orbital plane.
Symbol = As the angular momentum is a vector quantity, it is denoted by symbol L. Units = It is measured in SI base units: Kg m²s⁻¹. Dimensional formula = M L² T⁻¹ Formula to calculate angular momentum (L) = mvr, where m = mass, v = velocity, and r = radius.
The direction of the angular momentum vector is directed along the axis of rotation given by the right-hand rule.
Angular momentum of a body has both magnitude and direction. So it is a vector quantity. It is denoted by the symbol 'L'. A vector that does not change its sign if the coordinate system is changed into a new system by the reflection in the origin is known as an axial vector.

Determining the Direction of the Velocity Vector The direction of the velocity vector is simply the same as the direction that an object is moving. It would not matter whether the object is speeding up or slowing down. If an object is moving rightwards, then its velocity is described as being rightwards.
(d) perpendicular to the orbital plane.
1 Answer. hence graph is straight line, constant slope and passing through origin.
When a mass is rotating in a plane about a fixed point, its angular momentum is directed along the axis of rotation.
