Question

if you want to know how fast an object is going at a particular moment, which type of motion graph should you examine?
velocity vs. time
position vs. time
force vs. time
acceleration vs. time

Explanation:

Velocity represents the rate of change of position and gives the speed of an object at a particular moment. A velocity - vs - time graph directly shows the velocity values at different times. Position - vs - time graph gives position information and its slope represents velocity but not as directly. Force - vs - time and acceleration - vs - time graphs do not directly tell about the speed at a moment.

Answer:

Velocity vs. Time
