Projectile motion refers to the motion of an object after it is struck and sent forward. Which term describes this motion?

• A. Projectile motion
• B. Gravity
• C. Moment of inertia
• D. Absorption

Answer: (A)

Projectile motion describes the path of an object after it is launched and moves under gravity, creating a curved trajectory. When air resistance is neglected, the horizontal motion is essentially constant while the vertical motion accelerates downward due to gravity, producing a parabolic path. Gravity is the force that shapes the curve, not the description of the motion itself. Moment of inertia relates to rotation and how a body resists changes in its spin, which isn’t what describes the path of a launched object. Absorption involves energy transfer or material properties, not the motion through space. So the motion in question is projectile motion.
