M4 Real-World Physics Discussion
The topic I chose to discuss for this week is Buoyancy and Buoyancy
Force. Buoyancy Force is the upward force that is exerted by a fluid on a
substance that is partly or completed submerged in it (Ostdiek & Bord,
2018). An example of how this works is if you were to put a piece of wood
and a rock in a body of water. The rock is going to immediately sink, and
the piece of wood is going to float. The rock is going to sink because the
weight is greater than the buoyancy force. The wood however will stay
floating because the buoyancy force is much greater than the weight.
An everyday example of buoyancy is cargo ships. Cargo ships transport
goods all over the world and are completely loaded to the max weight.
Even when the cargo ships are not loaded, they still weigh 100,000 tons
on average but can carry up to 220,000 tons loaded. These ships are able
to withstand rough and unpredictable seas while carrying this heavy load
through the vast oceans due to perfect engineering and design for having
the correct buoyancy force. Each ship takes tons of engineering man-
hours to ensure the design of the ship will perform the way it is intended
to.
Buoyancy and Bernoulli's principle are important to understand how an
aircraft produces lift with the use of its wings. In order for a plane to fly
the plane needs to displace a mass of air down that is equal to the
aircraft's mass, and this must happen each second (zhou, 2020). Planes
are also essentially floating on a cushion of air. The reason they are
essentially floating on a cushion of air is because of how the wings are
shaped in order to push the air downwards underneath the wing.
