Parsec is an astronomical unit of measurement which is commonly used in galactic or extra galactic scales.
It is defined as the distance of an astronomical object from the Sun which has a parallax of 1 arcsecond.
For example
The distance between the Sun and the star Proxima Centauri is around 1.29 Parsecs.
1 Parsec = 3.08567758 × 1016 meters

Condition of pure rolling: Pure rolling occurs when rolling is done without any resistance. Pure rolling is a case when the point of lowest contact of rolling body with ground remains at rest and body is deliberated to be rotating about this point of contact.

By the second equation of motion,
s = ut + 1/2 at 2
S is directly proportional to the time only when there is no external force acting on it.
In the absence of external force, acceleration ‘a’ of the object becomes zero and the equation of motion becomes
s = ut
Since acceleration is zero so speed ‘u’ of the object remains constant.
Hence, it can be concluded that S is directly proportional to t.

Moment of inertia is defined as the quantity expressed by the body resisting angular acceleration which is the sum of the product of the mass of every particle with its square of a distance from the axis of rotation.
Factors that affect the moment of inertia
The moment of inertia depends on the following factors,
- The density of the material
- Shape and size of the body
- Axis of rotation (distribution of mass relative to the axis)
