Vector:
they have a definite magnitude (size) and definite direction. E.g.
displacement, velocity, acceleration, force etc.
Scalar:
they have a definite magnitude but don’t have any definite direction. E.g. Distance, speed, work, energy, power,
electric charge
Tensors:
They have different magnitudes in different directions, e.g. Moment of inertia,
stress etc
Linear
momentum: It is the quantity of motion which a body possesses and is
measured as the product of the mass and
Velocity of the body
Impulse:
The total change in momentum is called the impulse. If a very large force acts
for a very small time, the product of force and the time is equal to the
impulse.
Inertia:
The inability of a body to change by itself its state of rest or state of
uniform motion along a straight line is called inertia of the body. The inertia
of a body is measured by its mass. Heavier the body, greater is the force
required to change. It’s state and hence greater is its inertia. Inertia of a
body may be inertia of rest, inertia of motion or inertia of direction.
