Reference Point and Position

Introduction

To describe the location of an object, we need a fixed or chosen point for comparison. This chosen point is called the reference point. The location of the object with respect to this reference point is called its position.

Position

The position of an object tells us where the object is located with respect to a reference point. The reference point is arbitrary. It can be home, school, temple, church, mosque, park, or any other fixed point.

Reference Point

A reference point is chosen according to the situation. For example, if you are moving from home to school, then home may be taken as the reference point.

Explanation of the Concept

Suppose you are moving from home to school. If we take home as the reference point, then your position at any instant can be described by your distance and direction from home.

Key Points

• The position of an object is its location relative to a reference point.
• A reference point can be chosen according to convenience.
• Home, school, temple, church, mosque, or any fixed place can be a reference point.
• Position is described by distance and direction.

Examples

• The school is 2 km east of the home.
• The temple is 500 m north of the home.
• The mosque is near the school.
• If you move from home to school, your position changes continuously.

Exam Points

• Position means the location of an object with respect to a reference point.
• The reference point is arbitrary.
• A reference point may be home, school, temple, church, mosque, or any fixed point.
• Position is defined by distance and direction.

Conclusion

Thus, the position of an object tells us where it is located with respect to a chosen reference point. Therefore, to describe the position of any object clearly, we need a reference point along with distance and direction.
