When a projectile moves upward , its vertical component of velocity?
Correct answer: A. Decrease
- A. Decrease
- B. increase
- C. Remains same
- D. None of these
Explanation
While a projectile rises, gravity acts downward and reduces its upward vertical velocity according to vy = uy - gt, where velocity is measured in m/s and acceleration in m/s^2. The likely mistake is choosing increase by assuming the upward motion itself produces upward acceleration, but gravity always accelerates it downward.

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.
