What is the difference between angular momentum and linear momentum?

Hint: Momentum is defined as the product of the mass and velocity of objects. Momentum is a vector quantity which has both magnitude and direction. Momentum (p) =mv and the dimensional formula of momentum is\[ML{{T}^{-1}}\]. The SI unit of momentum is kilogram meter per second$(kgm{{s}^{-1}})$ and momentum is a conserved quantity.

Complete answer:
Newton’s second law states that the rate of change of momentum of a body with respect to time is directly proportional to the applied force in the same direction as the applied force and inversely proportional to mass.
Angular momentum which is defined as the inertia of rotation motion and in angular momentum the objects change their position and also their direction with respect to the reference point. Angular momentum which is the property of objects.SI unit of angular momentum is $kg{{m}^{2}}{{s}^{-1}}$
Angular momentum (L) is given by:
$L=mvr$
Where r=radius
m=mass
v=velocity
Linear momentum which is defined as the inertia of translation motion and in linear momentum objects which move in the same direction and position with respect to reference point. Linear momentum which is also the property of objects. The SI unit of linear momentum is kilogram meter per second$(kgm{{s}^{-1}})$
Linear momentum is given by:
$p=mv$
Type of motion which is related to angular and linear momentum is different.

Note:
Student’s linear momentum is also called translational momentum or momentum and from the general law of physics we get to know that in momentum the motion cannot change in an isolated object; this further implies that the system remains constant. As the linear momentum increases the mass and velocity of objects also increases.
