Force: Force has magnitude as well as direction. The direction towards which the force is applied is known as the direction of force.
Force →F=m→a;→a = acceleration m = mass
Angular momentum: It is a vector quantity, and it is product of moment of inertia and the angular velocity about an axis.
It is represented by, →L=I→ω;I = moment of inertia →ω = angular velocity
Work done (W): Work is the product of the component of the force in the direction of the displacement and the magnitude of this displacement.
w=→F.→s;→F = Force, →s = displacement
W=Fscosθ;θ=angle between→F and →s. We know that the dot product of two quantities is always a scalar quantity.
Current: Current is a scalar quantity because current doesn’t obey the law of addition of vectors.
Linear momentum: Momentum is a vector quantity. It has both magnitude and direction. It is defined as →P=m→v; m = mass, →v = velocity
Electric field: Electric field is a vector quantity as it is defined as electric force per unit positive charge, and force is vector quantity. Hence electric field is also a vector quantity.
Average velocity: Average velocity is a vector; it has both magnitude and direction.
Average velocity is defined as total displacement divided by time.
Magnetic moment:
The magnetic moment is a vector relating torque of an object to the magnetic field. This is mathematically represented as:
→τ=→m×→B; →m = magnetic moment, →B = magnetic field
Relative velocity: Relative velocity is a vector quantity, it is velocity of an object with respect to the rest frame of another object.
In the given list in the question work and current are scalar quantities.
