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.

see earlier answer

the components of a vector are the parts of the vectors that are to each other.
