Question

Fill in the blanks:
The reference point from which the distance of a body is measured is called__________.

Answer 1

Hint: Reference point is an object that stays in place. An object is in motion if it changes position relative to the reference point. The reference point is also known as origin. A positive or negative sign can be used to show the position of an object relative to the reference point.

Complete step-by-step answer:
We will understand this concept by considering one example.
How would you tell your home address to your friend while you are on call? You usually give directions considering shops like take turns from that chicken shop and like that but if other people won’t understand it then this calls frustration. Solution is to take GPS.it is a lot easier. If you closely look into GPS, you will see a reference point. So when you want to locate something you need a point which must be unique or a point which is known to someone and the point, you are telling the address and that point must be your reference point.
So in physics, when we try to define a Point of our body then we need another point by which we will tell distance, displacement, or direction, etc. to pinpoint the location. The other point is called a reference point.
So the reference point from which the distance of a both measured is called origin.
In physics, origin is often replaced with observer.
In a circle, graph, square, any geometrical shape also you see an origin.

Note: Origin is a point in space (2D or 3D), regardless of the type of geometry which you are using stays still and doesn't move. A rigid framework, such as the earth, the celestial sphere or any other platform, relative to which position, motion, etc. in a system may be measured. Reference point is a place or object used to compare in order to determine if an object is in motion.
