This is the video we did in our class. The idea is that you check the amount of water (VOLUME) displaced when we introduce the glass with rocks. Depending on the weight of this glass if the volume is the same than upthurst the glass will float.
The second time when I introduce more rocks the volume and the weight of the glass is practically the same, it’s close to sink.
This is a cargo being loaded. You can see the amazing control of the weight in this huge ships.
Look at this video and realise how the effort rubber bands do on a mellon. Of course your real shight misses lots of frames and images we don’t see very well. Here you can see how contact forces affect objects, the flexible rubber bands produce a contact force on the watermelon and after placing lots of rubber bands the fruit doesn’t resist the force of the rubbers.
