Question

which describes what a velocity/time graph would look like with no acceleration? curved line on a upward slope straight line on a downward slope straight line with zero slope curved line on a downward slope

Explanation:

Acceleration is the rate of change of velocity. On a velocity - time graph, the slope represents acceleration. When there is no acceleration, the velocity is constant. A constant velocity is shown as a straight line with zero slope on a velocity - time graph.

Answer:

straight line with zero slope
