To calculate weight in water, subtract the weight of the object when submerged in water from its weight in air. Use the formula: Weight in Water = Weight in Air - Buoyancy Force. The buoyancy force equals the weight of the displaced water. For precise results, use a spring scale to measure both weights accurately.

FAQs & Answers

  1. What is the formula to calculate weight in water? The formula to calculate weight in water is: Weight in Water = Weight in Air - Buoyancy Force.
  2. How is buoyancy force calculated? Buoyancy force is calculated by finding the weight of the displaced water. This can be determined using the volume of the object submerged multiplied by the density of the water.
  3. Why is it important to measure weights accurately in water? Accurate measurements in water are crucial for precise calculations of buoyancy and weight, particularly in scientific experiments and engineering applications.
  4. What tools can be used for measuring weight in air and water? A spring scale is commonly used for measuring weight in both air and water to ensure precise results.
