Enter your initial velocity, launch angle, and other parameters into the calculator to determine the trajectory of the projectile.
Trajectory Calculation Formula
The following formula is used to calculate the range of a projectile:
Range = (Initial Velocity² * sin(2 * Launch Angle)) / g
Variables:
- Range is the horizontal distance traveled by the projectile (m)
- Initial Velocity is the speed at which the projectile is launched (m/s)
- Launch Angle is the angle at which the projectile is launched (degrees)
- g is the acceleration due to gravity (approximately 9.81 m/s²)
To calculate the range, you need to know the initial velocity and the launch angle. The sine function is used to account for the angle of launch, which affects how far the projectile will travel.
What is Projectile Motion?
Projectile motion refers to the motion of an object that is thrown into the air and is subject to the force of gravity. The path that the object follows is called its trajectory, which is typically a parabolic shape. Understanding projectile motion is essential in various fields, including physics, engineering, and sports science.
