Use the following simulation to explore the conservation of momentum. In the simulation we asume that the collisions are elastic, that is, the total kinetic energy of the two bodies after the collision is equal to their total kinetic energy before the collision.
Things to try:
You can drag points A and B to change the position of the balls.
Activate the box Axes to help you set the position of the balls.
Change the velocity by activating Velocity box.
Change the mass (kilograms) of the balls by dragging the sliders m1 and m2.
Activate the Momentum box to show vectors.
Sorry, the simulation is not supported for small screens.
