Question:medium

Which of the following statement is correct in connection with projectiles?

Show Hint

The horizontal component of the velocity of projection ($u \cos \alpha$) always remains constant throughout the flight because there is no horizontal force (like air resistance) acting on it.

  • A path traced by a projectile in space is known as trajectory.
  • The velocity with which a projectile is projected is known as velocity of projection.
  • The angle with the horizontal at which a projectile is projected is known as angle of projection.
  • all of the above
Show Solution

The Correct Option is D

Solution and Explanation

Projectile motion problems rely on three basic pieces of vocabulary that describe the launch conditions and resulting path, and this question is really checking whether each term is correctly matched to its meaning.

The curved path an object follows once launched is called its trajectory, a purely geometric description of the route through space that has nothing to do with speed or angle on its own.

Separately, the speed given to the object at the moment of launch is its velocity of projection, a distinct concept from the trajectory since it describes the initial push rather than the resulting path.

And the direction of that initial push, measured from the horizontal, is the angle of projection, a third independent piece of information needed to fully describe the launch.

Since all three terms are being used in their correct, standard sense here with nothing swapped or misapplied, there's no single false statement to isolate, all three hold true together.

So the correct answer is all of the above.
