In the example, the railway station serves as the reference point to describe the position of the school, which is stated as being 2 km north of the railway station.

Specifying the position of an object with respect to a reference point involves stating the distance, direction, or both between the object and the reference point.

We describe the location of an object by specifying a reference point, known as the origin, and providing measurements or directions relative to that point.

The motion of objects along a straight line is described using concepts such as distance, displacement, speed, velocity, and acceleration, along with equations and graphical representations.

Most motions involve various types of movement, such as straight-line motion, circular motion, rotation, or vibration, and can often involve combinations of these.
