Life-Size Collisions
Life-Size Collisions

Students will observe "explosions," in which one student on a dynamics cart pushes another. From this, they will confirm the relationship between mass and velocity in determining momentum. They will also reinforce the idea of a closed system by experimenting...

The Bouncing Dart
The Bouncing Dart

The Bouncing Dart is a specially designed pendulum with one elastic end and one inelastic end. Students will collide each end with a massive (1kg or more) cart, observing the pendulum's motion and measuring the distance the cart moves. They...
