Which choice is a valid way to construct a motion diagram?
question 8 options:
add together the average speeds of the various objects in motion.
take a series of photographs at equal time intervals of a moving object, perpendicular to the direction of motion; overlay the images to see how the position changes with time.
draw vectors to represent the speeds involved.
add vectors in a head-to-tail manner to determine the resultant vector.

A valid way to construct a motion diagram is to take a series of photographs of a moving object at equal time intervals of time, perpendicular to the direction of motion and overlaying the images to observe the position change with time.

Explanation:

In order to develop a motion diagram, a coordinate system, a zero and appropriate scale should be chosen. Generally positions to the right of the origin are considered positive. Velocity can be determined from the motion diagram by plotting velocity vectors.

The acceleration of an object can also be calculated from the motion diagram.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
