Projectile Motion, X and Y Displacements
Here is a screen shot of the demonstration:
 |
The ball will move every second.
You should notice that the x-displacements are constant per second. 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. 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.
