FAQs on Archimedes Principle & Buoyancy Video Lecture - Physics for EmSAT Achieve

1. What is Archimedes Principle?
Ans. Archimedes Principle states that an object partially or fully submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid it displaces.
2. How does buoyancy work according to Archimedes Principle?
Ans. Buoyancy acts in the opposite direction of gravity, causing objects to float when the buoyant force exceeds the weight of the object.
3. How can we calculate the buoyant force using Archimedes Principle?
Ans. The buoyant force can be calculated by multiplying the density of the fluid, the acceleration due to gravity, and the volume of the fluid displaced by the object.
4. Can objects sink in a fluid even if they follow Archimedes Principle?
Ans. Yes, objects can sink in a fluid if their density is greater than that of the fluid, causing the buoyant force to be less than the weight of the object.
5. What are some real-life applications of Archimedes Principle and buoyancy?
Ans. Some examples of real-life applications include ships floating on water, hot air balloons rising in the air, and submarines diving underwater.
