Respuesta :

let’s make this an arrow

from A to B, the arrow is flying up to the sky. from B to C, the arrow is coasting in the air for a short moment. from C to D, the arrow is plummeting back to the ground.

Motion graphs! Oh yes, I remember those.

I will be using the example of a remote-control car.

For Section AB:

The car starts moving steadily in one direction.

For Section BC:

The car has stopped moving.

And finally, for section CD:

The car has turned around and returned to the starting point at a steady pace.

I hope this answers your question.
