Question:
In a projectile motion shown in figure, which one of the following statements is NOT CORRECT?
In a projectile motion shown in figure, which one of the following statements is NOT CORRECT?
Show Hint
Compare the vertical and horizontal velocity at the launch point A and the highest point B.
Updated On: Nov 13, 2026
The acceleration in the vertical direction is same at points A and B .
The velocity is minimum at B .
The vertical velocity is same at A and B .
The horizontal velocity is same at A and B.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
A is the point of projection and B is the highest point of the trajectory.
Step 2: Check each statement
The acceleration is \(g\) downward everywhere. The horizontal velocity \(u\cos\theta\) stays constant. The speed is least at B because only the horizontal component is left.
Step 3: Vertical velocity
At A the vertical velocity is \(u\sin\theta\) while at B it is zero, so it is not the same.
Step 4: Result
The statement that the vertical velocity is the same at A and B is incorrect.
Final Answer:
The statement that the vertical velocity is the same at A and B is not correct. \[ \boxed{\text{(C) }\text{The vertical velocity is same at A and B.}} \]
