Projectile Simulator

Understanding the Projectile Motion Simulation

What is Projectile Motion?

In physics, projectile motion describes the path of an object (a projectile) launched into the air, assuming a uniform gravitational field and neglecting air resistance. This motion follows a parabolic curve, resulting from the combination of an initial velocity and the force of gravity.

How Does This Simulation Work?

This simulation allows you to visualize projectile motion by setting the initial velocity and launch angle. The simulation then calculates and displays the range, maximum height, and time of flight of the projectile.

The parameters you can adjust are:

• Initial Velocity (v₀): The speed at which the projectile is launched (in meters per second).
• Launch Angle (θ): The angle between the launch direction and the horizontal (in degrees).

Key Physics Equations

The simulation uses the following equations (expressed in AsciiMath):

• Range (R)

  The range is the horizontal distance the projectile travels. It is calculated as follows:

  `R = (v_0^2 sin(2 theta))/g`

  Where:

  • `v_0` is the initial velocity
  • `theta` is the launch angle (in radians)
  • `g` is the acceleration due to gravity (approximately 9.81 m/s²)

• Maximum Height (H)

  The maximum height is the highest point the projectile reaches. It is calculated as follows:

  `H = (v_0^2 sin^2(theta))/(2g)`

  Where:

  • `v_0` is the initial velocity
  • `theta` is the launch angle (in radians)
  • `g` is the acceleration due to gravity (approximately 9.81 m/s²)

• Time of Flight (T)

  The time of flight is the total time the projectile is in the air. It is calculated as follows:

  `T = (2 v_0 sin(theta))/g`

  Where:

  • `v_0` is the initial velocity
  • `theta` is the launch angle (in radians)
  • `g` is the acceleration due to gravity (approximately 9.81 m/s²)

Limitations of the Simulation

This simulation is a simplification of the real world. It does not take into account:

• Air resistance (drag)
• The Earth's rotation (Coriolis effect)
• Variations in gravity with altitude
• The shape and size of the projectile
