Motion Maps are helpful, creative tools for examining and demonstrating what information we have about how an object moves.
Motion Maps can be considered strobe light photography. Strobe photographs must have a lot of images based on one picture. Every painting is responsible for representing specific instants in time.
Besides all of these, there is a selected time gap (interval) in the middle of each image. (A similar pattern could be made by cutting out the frames of a movie and laying them on top of each other). Let me give you an example of a ball rotating consistently with the strobe, and the time interval settled to 1.00 seconds. This instance brilliantly describes the functioning of motion maps.
“One-dimensional plots that are constructed on a position line are commonly called Motion Maps.” Marks can show the Car’s position along the horizontal axis. The graph is drawn using different quantities like velocity, acceleration, and time.
In Motion Maps, we can concern ourselves with showing the object’s position and velocity at particular time intervals.
We can also determine the idea of acceleration, deceleration, or altering the direction.
To understand this, let us consider the Example of a Car: –
While drawing a graph for the moving Car, if the Car is moving horizontally, then the Car’s position can be shown by marks concerning time. Also, some arrows are used to illustrate the velocity and acceleration of the car graph.
The direction of velocity and acceleration can be represented by the arrows, while the magnitude of quantities is represented by
resultant volumes of hands.
Motion Maps are the best in the field to demonstrate or visualize the position, velocity and acceleration of the objects simultaneously.
Working Methodology in Motion Maps
Initial conditions are provided by the user (initial velocity, acceleration, draw interval), and the Car will move as accordingly:
As, v1=vf+vt+(1/2)at.t
Present position = last position + (velocity * time) + (1/2 * acceleration * time<sup>2</sup>).
According to the moving position of the Car, and by keeping all given conditions in mind, the model noticed and drew its position, acceleration, and velocity.
Positions are labeled as red spots.
Velocity
This is shown by blue arrows (vectors are physical quantities) that indicate both magnitude and direction.
Velocity is also a vector quantity.
A longer arrow will represent the increasing value of the velocity. The length of the hand depends upon the quantity of rate. As the velocity value increases, the size will increase too.
Succeeding to a standard line plot, the Car’s motion to the left is negative while the motion proceeding to the right is positive.
Acceleration
It is denoted by colored dots or arrows that are orange in color.
The direction of orange dots is reversed when acceleration becomes zero.
Likewise, Velocity, It is also a vector quantity. Arrows express acceleration for non-zeros. Also, both magnitude and direction have to be shown.
HOW TO READ GRAPH
INITIAL-VELOCITY is the beginning velocity,
ACCELERATION is the acceleration that will remain constant throughout time,
DRAW-INTERVAL is the time between note-down instances.
Before recording databases in a motion map, plots in two dimensions drawn between quantities like position Vs time, acceleration Vs time, and velocity vs time are included in this model.
Note, Car will not be shown after reaching borderlines.
Things to Do
You can compare graphs of different values also. For example, diagrams of two Cars moving along each other with different initial values can be reached.
You can notice positive acceleration interaction with initial negative velocity. The changing pattern should be seen between the three plots and motion maps.
By using increasing values of velocities and acceleration, you can check their separate motions and differences in
graphic diagrams.
You can also try to find those values that made the Car reach both the left and correct map borders before arriving at a stopping point.
