Lab #8.2 Mechanics: Chapter 8  Egg Toss
Lab #8.2 Mechanics: Chapter 8 Egg Toss

Purpose In this activity, you will investigate the effect that stopping time has on stopping force when momentum changes. Discussion Allowing an object to keep moving as it is being caught extends the stopping time which in turns reduces the...

Acceleration Force and Mass
Acceleration Force and Mass

Students love fast moving experiments, but higher speeds often require higher technology. That can challenge the budget and students’ ability to use the technology. These simple, but highly accurate photogates remove both barriers. No costly computers are needed, and set...

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...
