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.

Passengers inside the bus perceive their fellow passengers as being at rest because they are moving at the same velocity and direction as the bus.
