Weight Less (Under water!)
November 3, 2008 by claguna
Well, it sure beats dieting! Mike’s ingenious experiment confirms it! Objects weigh less when they are submerged in water! We used the Pasco force sensor to measure the weight of an object above the water and again after it had been submerged. Here is a challenge for you. Can you explain why the object weighs less under the water? Don’t forget to use the term, “buoyant force.”

An object weighs less under water because *buoyant force* causes the object to resist gravity.

Hey did you know that someone can be described as having a buoyant personality? What do you think that means? My friends son was buoyant when we went to the pool last summer, in both senses of the word!
