Question

Kinematics describes the motion of a particle . here what is meant by describing the motion ??? Why do we only describe for a particle????

Answer 1

Yes in kinamatics motion means a particle is moving with some speed with respect to time is known as motion if the position of the particle change with respect to time then it is meant as motion yes because it is only describe for point objects just like particle for exact calculation dude have doubt ask in comment box it's postion with some points in a reference frame the motion the motion of the particle takes place because when a particle change it's position with respect to time we call it variation of position takes place and change the coordinates of the reference frame so it change the path of the object and as a result we call it motion because motion means the Change of position with respect to time and in kinamatics we study the change in path of the particles with respect to time because we need exact data to find time speed velocity etc and it shows the creation of motion come from the term kinamatics as a change of position with respect to time
