Kinematics

Science that studies motion.

Kinematics: displacement

It is the distance in straight time between starting and the end point.

Kinematics: trayectory

It is the path that a moving body follows.

Kinematics: reference

The point of origin that you use to check the movement.

Kinematics: time

It is a magnitude to measure the duration of an event.

Velocity

Is the measurement of the rate at witch bodies move. It is a ratio between the displacement and the time used. Its SL= m/s.

Aceleration

Is the measurement of the rate which the velocity of a body varies. Is calculated as the ratio between the variation of velocity and the time used. Its SL= m/s2
