Question

Quizplus · Accepted Answer

Displacement is the change in position of an object, measured in a straight line from its initial position to its final position. In this case, the particle moves from x₁ = 30 cm to x₂ = - 40 cm. The straight-line distance between these two points is (40+30)cm = 70cm. However, the particle ends up at -40 cm, which means its final position is 70 cm in the negative direction from its initial position. Therefore, the displacement of the particle is -70 cm.

A Particle Moves from X1 = 30 Cm to X2

A Particle Moves from X₁ = 30 Cm to X₂
