A two dimensional motion under the acceleration due to gravity is known as
Correct answer: D. Projectile motion.
- A. Linear motion.
- B. Circular motion.
- C. Vibratory motion.
- D. Projectile motion.
Explanation
The correct answer is projectile motion. Projectile motion occurs when an object is thrown or projected into the air and moves along a curved path under the influence of gravity. It involves both horizontal and vertical motion components, making it two-dimensional. Linear motion is incorrect as it refers to one-dimensional movement. Circular motion is incorrect as it involves movement along a circular path. Vibratory motion is incorrect as it involves oscillations, not two-dimensional motion under gravity.

About Projectile Motion
Projectile motion combines uniform horizontal motion with vertically accelerated motion under gravity, assuming air resistance is neglected. Questions use the components of initial velocity to find time of flight, maximum height, horizontal range and position, while distinguishing projectile motion from general circular or one dimensional motion.
