Understanding Motion Graphs: Position, Velocity, and Time

The position time and velocity-time graphs represent the position occupied by a mobile object with respect to a reference system. Are also used to represent it's velocity over time. If we imagine that the mobile objects moves in a straight line, 2 types, of graph can be used:The distance (s) of the mobile object from the origin is always the same over time (t), which means the mobile object is at rest  The distance (s) increases uniformly over time (0). On the green line, the mobile object leaves the origin (0), but on the red line begins to move at a distance (s) from the origin  The distance to the ongin (0) is reduced over time (1) Therefore, the mobile object is moving towards the reference point..Velocity time graph ..It indicates the velocity of the mobile object at any time.The velocity (v) does not change over time (r).The velocity (v) increases uniformly over time (t).

Trajectory; an imaginary line joining the positions which the mobile object goes though ..Space covered (s): the distance covered by the mobile object on the trajectory..The type of motion depends on the trajectory if the trajectory is a straight line, it is a linear motion. On the other hand if the trajectory is a curve it is a circular motion...Velocity: is a physical magnitude which tells us how fast a body is moving.Therefore velocity is the relationship between the space covered by the mobile object and the time taken to cover it. The velocity is called average velocity..Graphical representations,,The position time and velocity-time graphs represent the position occupied by a mobile object with respect to a reference system. Are also used to represent it's velocity over time.
