1. What is Horizontal Velocity?

Horizontal velocity is the component of an object's velocity that is parallel to the ground. When an object is launched at an angle, its velocity can be broken down into horizontal (v_x) and vertical (v_y) components.

2. How Does the Calculator Work?

The calculator uses the horizontal velocity equation:

Where:

• \( v \) — Total velocity (m/s)
• \( \phi \) — Angle of rotation (degrees)
• \( v_x \) — Horizontal velocity component (m/s)

Explanation: The equation calculates the horizontal component of velocity by multiplying the total velocity by the cosine of the launch angle.

3. Importance of Horizontal Velocity Calculation

Details: Calculating horizontal velocity is essential in projectile motion analysis, engineering applications, ballistics, and sports science. It helps determine how far a projectile will travel horizontally.

4. Using the Calculator

Tips: Enter velocity in m/s and angle in degrees (0-360). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What happens at 0 degrees?
A: At 0 degrees, all velocity is horizontal (v_x = v) since cos(0) = 1.

Q2: What happens at 90 degrees?
A: At 90 degrees, horizontal velocity is zero (v_x = 0) since cos(90°) = 0.

Q3: How does angle affect horizontal velocity?
A: Horizontal velocity decreases as the angle increases from 0° to 90°.

Q4: What units should be used?
A: Velocity should be in meters per second (m/s) and angle in degrees.

Q5: Can this be used for 3D motion?
A: This calculates only the 2D horizontal component. For 3D motion, additional calculations are needed.
