The distance travelled is given by:

Correct answer: A. Area under speed-time graph

  • A. Area under speed-time graph
  • B. Area under distance-time graph
  • C. Slope of velocity-time graph
  • D. Slope of distance-time graph

Explanation

The correct answer is the area under the speed-time graph, which represents the distance traveled. This is because the area (calculated as speed multiplied by time) gives the total distance covered during the period. The other options are incorrect because:The area under a distance-time graph doesn't convey any meaningful information about distance traveled.The slope of a velocity-time graph indicates acceleration.The slope of a distance-time graph indicates speed, not the total distance traveled.

About Force and Motion

Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
