Question

For a projectile motion, the angle between the velocity and acceleration is minimum and acute at

• A. Only one point
• B. Two points
• C. Three points
• D. Four points

Answer 1

The Correct Option is A

In projectile motion, the center of acceleration is always directed toward the Earth's center. At the peak point of the trajectory, the angle between the velocity and acceleration is 90 degrees because the vertical component of velocity becomes zero. As a result, the velocity is at its minimum and is purely horizontal. This 90-degree angle occurs only at the highest point, making it the sole instance where the angle between velocity and acceleration is exactly perpendicular. At all other points, the angle is acute.

The Correct Answer is (A): Only one point
