Projectile Motion, X and Y Displacements








Time interval:

View markers:

This is an interactive animation that shows the x- and y-displacements for an object traveling in projectile motion without air resistance near the surface of a planet, such as Earth. You can adjust the following parameters:

  • vxo - This is the original x-velocity of the projectile.
  • vyo - This is the original y-velocity of the projectile.
  • ay - This is the constant y-acceleration of the projectile, the acceleration due to gravity.
  • Time interval - This is the length of time between which the displacement markers are drawn.
  • View markers - These checkboxes control the visibility of their respective displacement markers.
  • Pause/Resume - This button pauses or resumes the motion of the animation.

 

You should notice that the x-displacements are constant per time interval.

The x-velocity of projectile motion is constant.

This is because the x-velocity of the projectile is constant. The x-velocity is constant because there is no x-acceleration. There is no x-acceleration because there is no x-force. In other words, gravity does not pull sideways.

 

You should notice that the y-displacements change per second.

The y-velocity of a projectile is not constant.

This is because the y-velocity of the projectile is changing. The y-velocity is changing because there is a y-acceleration. There is a y-acceleration because there is a y-force. In other words, gravity pulls downward.
