MCQ: Velocity-Time Graphs - Class 9 MCQ

• The area under the velocity-time graph represents the total change in position over time.
• This area can be positive or negative, indicating direction, hence it measures displacement.
• Displacement is the net change in position, while distance measures the total path traveled.
• Speed is the magnitude of velocity, and acceleration measures the change in velocity over time.
• Thus, the correct answer is displacement as represented by the area under the graph.

Area under a s-t graph represents a physical quantity which is Distance.
Area under the s-t graph will always give distance.
And distance has a unit of m.

The slope of velocity- time graph represents the acceleration. Since straight line is inclined to the time axis, slope is uniform  and constant, acceleration will be uniform.
