Experiment for middle school with Uniform Acceleration

Click For Summary
An experiment for middle school students on uniform acceleration can effectively utilize Galileo's Inclined Plane to demonstrate principles of motion. This method simplifies the concept of acceleration due to gravity while allowing students to observe the effects of inclination on speed. The discussion highlights the need for a smooth surface to ensure accurate results. The original idea of using a catapult was deemed too complex for reproduction in a classroom setting. Overall, the Inclined Plane experiment is presented as a practical and educational alternative.

1. I must present an experiment for middleschool children about Uniform Acceleration or paraboles to teach them how it works.


I've tried some stuff but maybe to complicated to fabricate or reproduce, for example, I wanted to do a catapult that made a small parabole and predict where it would fall or how high would it reach but the only catapult guides were overly complicated.

Help really appreciated.

Hi Alexi! Welcome to PF! :smile:

How about good ol' Galileo's Inclined Plane experiment?

(google it! :wink:)
 
Thanks! Let me talk to my partners about this but definitely a good idea.

But I guess the surface must be as smooth as it can be (in the inclined plane that proves that acceleration of gravity is the same but can be slowed down by the inclination).
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
