A projectile is launched in air with certain angle; its velocity is maximum at:
Correct answer: A. Point of projection
- A. Point of projection
- B. Highest point
- C. Between launching and highest point
- D. At all points
Explanation
The vertical component decreases as the projectile rises and is regained on the way down, so the speed is greatest at launch and again on landing at the same height, and least at the top where only the horizontal component remains. Neglecting air resistance, the landing speed equals the launch speed. This follows directly from energy conservation, since the kinetic energy is greatest where the height is least.

About Projectile Motion
Projectile motion combines uniform horizontal motion with vertically accelerated motion under gravity, assuming air resistance is neglected. Questions use the components of initial velocity to find time of flight, maximum height, horizontal range and position, while distinguishing projectile motion from general circular or one dimensional motion.
