1. What is the Distance Formula?

The distance formula calculates the horizontal distance traveled by a projectile launched with a given initial speed at a specific angle, under constant gravitational acceleration. It's derived from the equations of projectile motion in physics.

2. How Does the Calculator Work?

The calculator uses the distance formula:

\[ Distance = \frac{Speed^2 \times \sin(2\theta)}{g} \]

Where:

\( Speed \) — Initial velocity of the projectile (m/s)
\( \theta \) — Launch angle (degrees)
\( g \) — Gravitational acceleration (m/s²)
\( \sin(2\theta) \) — Sine of twice the launch angle

Explanation: The formula calculates the maximum horizontal distance achieved by a projectile launched from ground level, assuming no air resistance and constant gravitational acceleration.

3. Importance of Distance Calculation

Details: Accurate distance calculation is crucial for various applications including sports analysis, engineering projects, military targeting, and physics education. It helps predict projectile trajectories and optimize launch parameters.

4. Using the Calculator

Tips: Enter speed in m/s, angle in degrees (0-90), and gravitational acceleration in m/s². All values must be valid (speed > 0, angle between 0-90, gravity > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why is the angle doubled in the formula?
A: The sin(2θ) term comes from the trigonometric identity that maximizes range at 45 degrees. Doubling the angle creates the optimal relationship between vertical and horizontal motion components.

Q2: What is the optimal angle for maximum distance?
A: 45 degrees provides maximum distance when launching from and landing at the same height, as sin(90°) = 1, which is the maximum value.

Q3: Does this formula account for air resistance?
A: No, this is an idealized formula that assumes no air resistance. In real-world applications with significant air resistance, actual distance will be less than calculated.

Q4: Can this be used for objects launched from height?
A: This specific formula applies only to projectiles launched from ground level. Different equations are needed for objects launched from elevated positions.

Q5: How does gravity affect the distance?
A: Greater gravitational acceleration reduces the distance traveled, as the projectile is pulled downward more quickly. The distance is inversely proportional to gravitational acceleration.
