Which of the following remains constant for a projectile fired from the earth ?

Options

  1. AMomentum
  2. BVertical component of velocity
  3. CKinetic energy
  4. DHorizontal component of velocity

Correct answer

D. Horizontal component of velocity

Step-by-step solution

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.
