The motion of a car on a position-time graph is represented with a horizontal line. What does this indicate about the car's motion? ОА
It's not moving
OB. It's moving at a constant speed.
OC It's moving at a constant velocity.
OD. It's speeding up.

mass and volume are the answers you are looking for

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
