1. Initial Velocity (v₀): This is the speed and direction of the projectile when it is launched. You need both the magnitude (speed) and the angle (direction relative to the horizontal).
2. Launch Angle (θ): This is the angle at which the projectile is launched relative to the horizontal.
3. Acceleration due to Gravity (g): This is the constant acceleration acting on the projectile due to gravity, which is approximately 9.8 m/s² on Earth.
Formula:
The range (R) of a projectile can be calculated using the following formula:
R = (v₀² * sin(2θ)) / g
Explanation:
* v₀² * sin(2θ): This part of the formula calculates the horizontal component of the projectile's initial velocity, which is directly related to the distance it will travel.
* g: This accounts for the deceleration due to gravity acting on the projectile vertically.
Important Notes:
* This formula assumes that air resistance is negligible.
* The range is maximum when the launch angle is 45 degrees.
* The formula assumes that the projectile starts and ends at the same height. If the projectile is launched from a height, the formula needs to be adjusted.
