MCQ: Velocity-Time Graphs - Question 1

The area enclosed by velocity-time graph and the time axis will be equal to the magnitude of

Detailed Solution for MCQ: Velocity-Time Graphs - Question 1
  • 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.
