Use our Projectile Motion Calculator to compute the range, maximum height, and time of flight for a projectile launched with a given initial velocity and angle. Ideal for physics students and educators.
Enter the initial velocity, angle of projection, and height.
How to use this Projectile Motion Calculator 🤔
There are input fields for Initial velocity \((u)\), Angle of lanuch \((θ)\), Initial height \((h)\), Acceleration due to gravity \((g)\), Range \((R)\), Maximum Height \((H)\), and Time of Flight \((T)\). Enter the initial velocity, angle of projection, and height..
The calculator uses the formula, substitues given values, and calcuates the missing value.
The missing value is calcuated and displayed in the input field. Also, the caculation is displayed under the input section.
What is Projectile Motion?
Projectile motion refers to the motion of an object that is launched into the air and moves under the influence of gravity. The object follows a curved path known as a parabola. Key aspects of projectile motion include the horizontal range, maximum height, and total time of flight.
Calculating Parameters of Projectile Motion
Projectile motion involves several key formulas that help determine different aspects of the motion:
Horizontal Range (R): The total distance traveled horizontally.
\( R = u \cdot \cos( θ ) \cdot \left( \frac{ u \cdot \sin( θ ) + \sqrt{ \left( u \cdot \sin( θ ) \right)^2 + 2 \cdot g \cdot h } }{ g } \right) \)
Maximum Height (H): The highest point reached by the object during its motion.
\( H = h + \frac{ u^2 \cdot \sin^2( θ ) }{ 2 \cdot g } \)
Total Time of Flight (T): The total time the object remains in the air.
\( T = \frac{ u \cdot \sin( θ ) + \sqrt{ \left( u \cdot \sin( θ ) \right)^2 + 2 \cdot g \cdot h } }{ g } \)
In these formulas, the parameters are defined as follows:
u: The initial velocity, or the speed at which the object is launched.
θ: The angle of projection, or the angle at which the object is launched relative to the horizontal.
g: The acceleration due to gravity, typically taken as 9.8 m/s².
h: The initial height from which the object is launched.
