Length of the path is equal to the magnitude of the displacement of that particle. Shape of the path possible is
Correct answer: D. Straight line
- A. Area
- B. Area of a circle
- C. Parabola
- D. Straight line
Explanation
The correct answer is Straight line. When a particle moves in a straight line, the length of the path it travels is exactly equal to the magnitude of its displacement because both are defined by the direct distance from the initial to the final position. In contrast, for any other shape such as circles, triangles, or parabolas, the path length involves additional distances that make it greater than the displacement. Hence, only a straight line can equate the path length to the displacement magnitude.

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.
