What is Buoyancy?

  1. 1. Buoyancy Roads, Rails and Race cars
  2. 2. What Forces act on a Boat? Gravity Buoyancy
  3. 3. Buoyancy Definition • The force on a body that allows it to float or to rise when submerged in a fluid • The buoyant force exerted on an object by a fluid is equal to the weight of the fluid the object displaced
  4. 4. Fun Tips • Buoyancy always acts through the center of the volume of the object displacing the fluid • The center of mass of the boat should be well below the center of submerged volume of the boat to prevent the boat from tipping – This can be demonstrated with a tall bobber and a weight. If the weight is mounted on the top of the bobber, the bobber will tip upside down. If it is mounted on the bottom, it will stay upright.

  6. 6. Activity – Penny Boats • Construct your penny boat using only one piece of the heavy duty aluminum foil provided • Predict how many pennies your boat will hold: _______ • Slowly add pennies to your boat. Once water enters the boat, or if any part of the boat touches the bottom of the container, your turn is over • The last penny added will not count in the total amount held
