What is the Kinematics in one dimension?

#15453

Answer: It deals with the positions and motions of objects as a function of time, without regard to the causes of motion. Kinematics also involves the relationships between the quantities acceleration (a), displacement (d), velocity (v), and time (t). Acceleration displacement and velocity are vector since they contain both direction as well as magnitude. Displacement is change in position of the object, Velocity is a vector expression with a magnitude equal to the speed travelled and with an indicated direction of motion. Average velocity is mathematically defined as
Average velocity= (total displacement)/(time elapsed)
The rate of change of velocity is acceleration and is given by the following equation:
Average acceleration = (Final velocity-intial velocity)/(time elapsed)
Acceleration units are expressed as length per time divided by time such as meters/second/second or in abbreviated form as m/s 2.
