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 force acting on the object. In this lab students will put this theory to the test as they throw an egg to another student who must catch it with only their bare hands from an increasing distance. Who will figure out the principals of impulse and who will end up with egg on their face?

Required Equipment

The “garbage bags” required for this lab are any plastic bags large enough to construct plastic ponchos out of. The “masking tape” required for this lab is any tape that can be used to help hold the ponchos together. The quantity of “eggs” for this lab depends on how many repetitions of this exercise you wish to perform. A suggested amount would be 18 per lab group. It is suggested that this lab be done outdoors on a playing field (soccer, football, etc.)

Acceleration Force and Mass

Stephen ReaStudents 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 up is easy. Students literally ‘get up to speed’ fast!

Stephen Rea has been teaching physics and honors physics at both the high school and college level since 1980. Currently at the University of Michigan, Dearborn, he was the Michigan State Science Teacher of the year in 1994.

Using the Timer & Photogates in the Classroom!

Arbor Scientific’s photogates are highly effective for use in multiple experiments, including measuring acceleration and exploring projectile motion and Conservation of Momentum. Here are two examples:

Car and RampAcceleration: The Timer & Photogate system is perfect for measuring the acceleration of an object. This typically requires students to measure the time for the object to pass through each of the two photogates, plus the time to travel between them. The way that these values are displayed on the timer makes it easy for students to capture the data.

Conservation of Momentum: Experiments with Conservation of Momentum typically involve determining the speeds of two colliding objects, both before and after the collision. Using the timer memory feature, students can use the photogate system to obtain all four time values with precise accuracy. As an example of how they can be used, the teacher challenges students to use the photo-timer system with gliders on an air track and come up with an experiment that confirms Conservation of Momentum.

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 will conclude that elastic collisions transfer more momentum.
