Answer quick! a velocity vs time graph is a graph that shows the relationship between the velocity of an object over time. is plotted on the x-axis in seconds, and the of the object is plotted on the y-axis in meters per second.

Time is plotted on the x-axis in seconds, and the velocity of the object is plotted on the y-axis in meter per second

Explanation:

The velocity of a moving object is defined as the rate of change of distance with time. The graph described in this question is a graph of whose slope depicts acceleration. Acceleration is the rate of change of velocity with time.

So for a graph of velocity vs time, the Time which is the independent variable is plotted in the x-axis, while the velocity is the dependent variable, because its outcome is dependent on the time variable, hence it is plotted on the y-axis.

The dependent variable is one that is subject to the control of the experimenter (time) while the independent variable has its outcome dependent upon how the independent variable changes (velocity).

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
