👉 Motion in physics refers to the change in position of a body due to an applied force. The motion can be described by the velocity and acceleration vectors, which represent the rate at which the object is changing its velocity and the direction in which it's moving. Motions are fundamental to understanding the behavior of objects such as cars, trains, and planets. They also have applications in various fields like engineering, physics, and engineering mechanics where they provide a way to measure forces, velocities, and accelerations
