Which of the following remains constant for a projectile fired from the earth ?
- A Momentum
- B Vertical component of velocity
- C Kinetic energy
- D Horizontal component of velocity
Answer & Solution
Correct Answer
(D) Horizontal component of velocity
Step-by-step Solution
Detailed explanation
There is no acceleration in the horizontal direction during projectile motion and only gravitational acceleration \(g\) works in vertically downward direction. Hence, horizontal component of velocity remains constant.
