|
Ballistic simulator this virtual experiment is designed to let the student measure the relation between muzzle velocity (which determines projectile
energy), gravitational potential and the effects of frictional drag caused by wind speed blowing opposite to the direction the projectile is moving in |
| Bouncing
ball this applet shows the mass bouncing from the walls of the box. The mass moves under the force of gravity, and all collisions are elastic. The
angle at which the mass hits the surface is equal to the angle at which it leaves the surface |

Projectile motion
projectile motion,
illustrates the concept of projectile motion, it emphasizes the effect of gravity on the trajectory of a projectile. Both cannon
balls are deflected from a straight line trajectory by the same amount since gravity affects them the same way. This deflection is given by (1/2 g t2)
regardless of the velocity of the projectile |
