1. What Are Horizontal And Vertical Velocities?

Horizontal and vertical velocities are the components of a projectile's motion. The horizontal velocity (Vx) remains constant (ignoring air resistance), while the vertical velocity (Vy) changes due to gravity. These components help analyze projectile motion in two dimensions.

2. How Does The Calculator Work?

The calculator uses trigonometric equations:

\[ V_x = V \cos(\theta) \] \[ V_y = V \sin(\theta) \]

Where:

\( V \) — Initial velocity (m/s)
\( \theta \) — Launch angle (degrees)
\( V_x \) — Horizontal velocity component (m/s)
\( V_y \) — Vertical velocity component (m/s)

Explanation: The equations decompose the initial velocity vector into its horizontal and vertical components using trigonometric functions.

3. Importance Of Velocity Components

Details: Understanding velocity components is essential for analyzing projectile motion, calculating range, maximum height, flight time, and trajectory of projectiles in physics and engineering applications.

4. Using The Calculator

Tips: Enter initial velocity in m/s and launch angle in degrees (0-90°). The calculator will compute both horizontal and vertical velocity components.

5. Frequently Asked Questions (FAQ)

Q1: Why does horizontal velocity remain constant?
A: In ideal projectile motion (ignoring air resistance), no horizontal forces act on the projectile, so horizontal velocity remains unchanged throughout the motion.

Q2: How does vertical velocity change during flight?
A: Vertical velocity decreases due to gravity on the way up, becomes zero at the peak, and increases downward on the way down.

Q3: What is the relationship between angle and velocity components?
A: At 0° (horizontal launch), all velocity is horizontal. At 90° (vertical launch), all velocity is vertical. At 45°, horizontal and vertical components are equal.

Q4: Are these calculations affected by air resistance?
A: These equations assume no air resistance. In real-world applications with significant air resistance, both components would be affected.

Q5: Can these equations be used for non-projectile motion?
A: Yes, the same vector decomposition principles apply to any situation where you need to resolve a vector into its horizontal and vertical components.
