Topic - Physics for my Child - 5 FULL SENTENCES REQUIRED - TYPED ONLY

Instructions:

Describe the topics in one paragraph to your 5th Grader who has no familiarity with physics. You must NOT use physics terms without defining them at a level of explanation a 10 YEAR-OLD will understand. (For this assignment write ONE PARAGRAPH, written at a college level and with at least five sentences, including a topic sentence and three or more specific, accurate detailed supporting sentences, and a conclusion sentence.)

1) Behavior of Fluids, referring to fluids being composed of countless tiny particles, each of which obeys the physics of objects but because of their number, we instead examine the characteristics of the particles as a group. These bulk properties include pressure, temperature, and volume. For example, describe how pressure changes with force and area, Paraphrase Pascal’s Principle, Aristotle’s Principle, and Bernoulli’s Principle, explain why some things float and others sink (hot-air balloon, submarine, wood, rock, …). OR explain why pressure increases with depth.

Explanation / Answer

1. All matter is composed of particles. Now consider solids, these are composed of many particles together, so instead of studying propereties of single particle we study properties of all of them together as a solid, like mass etc. Similiarly, we study properties of fluid as properties of all the particles constituting the fluid together. These properties include the temperature ( degree of hotness or coldness of fluid), pressure ( related to force exerted on a unit area), and volume ( the space occupied by the fluid).
Pressure is directly related to the force a fluid appl;ies on the walls of the container and inversly related to the area it effects.

Pascals Principle : this states that in a fluid at same height from the surface of the fluid, the pressure ( force applied by fluid per unit area on the walls of the container) is the same for same fluid in any container.

Bernoulli's preinciple : this states that energy ( the potential of a n object to do some work) of a fluid depends on its height from the reference, its speed ( dis ance covered per unit time) and pressure at the point.

some things float on fluids while others sink depdning upon the weight carried by the objects in the given volume, If the weight carried by the fluid in the same volume of the object is more than the weight of the object then the object floatrs otherwise it sinks
