Which type of motion is correctly matched with its description?
AOne-dimensional motion — motion in a plane
BTwo-dimensional motion — motion along a straight line only
CThree-dimensional motion — motion involving length, breadth, and height
DProjectile motion — one-dimensional motion
Answer & Solution
Correct answer: C. Three-dimensional motion — motion involving length, breadth, and height
Three-dimensional motion occurs when the particle moves in all three spatial dimensions. One-dimensional motion is along a straight line, while projectile motion is a standard example of two-dimensional motion.
