  • Topic: Archimedes Principle.

  • Why do we weigh less in water?

  • Hey.

  • Looks like you have gained a lot of weight.

  • Come on.

  • Let us check your weight.

  • You weigh 132 pounds.

  • Alright.

  • Don't get stressed.

  • Check your weight in water.

  • Look.

  • It is much lesser.

  • Do you know why you weighed less in water?

  • The answer to this is based on Archimedes Principle.

  • Not that principal.

  • Archimedes Principle is a fundamental truth.

  • Which states that an object fully or partly immersed in a fluid.

  • Experiences an upward force called buoyant force which is equal to the weight of the fluid displaced by it.

  • It went over your head, right?

  • No worries.

  • Let me explain.

  • Gravity always pulls us downwards.

  • Hence, the weight of our body always acts downwards whether we are on ground or in water.

  • However, according to Archimedes Principle, when we are in water, we experience an upward force.

  • Buoyant force which is equal to the weight of water displaced by us.

  • This upward force cancels a portion of our weight causing us to weigh less in water.
