  -title: "Video: Sink or Float?"
  -description: """
    <p>All objects have a mass.</p>\r\n
    \r\n
    <p>The greater the mass, the greater the weight.</p>\r\n
    \r\n
    <p>Weight is the gravitational force that pulls an object downwards.</p>\r\n
    \r\n
    <p>But if we plunge an object in water, its weight seems less, as if the object had become lighter.</p>\r\n
    \r\n
    <p>In fact, its mass, and therefore its weight remain the same.</p>\r\n
    \r\n
    <p>However, a new force counteracts the weight.</p>\r\n
    \r\n
    <p>This force is called the buoyant force or simply buoyancy. The object experiences the combined action of both forces.</p>\r\n
    \r\n
    <p>If the buoyant force is less than the weight, the object falls, it sinks.</p>\r\n
    \r\n
    <p>Inversely, if the buoyant force is greater than the object&rsquo;s weight, it goes up.</p>\r\n
    \r\n
    <p>The object floats when these two forces are balanced.</p>\r\n
    \r\n
    <p>In any case, buoyancy is oriented upwards.</p>\r\n
    \r\n
    <p>Would it be possible to increase this force enough to make a heavy object float?</p>\r\n
    \r\n
    <p>The answer is &laquo; yes ! &raquo;</p>\r\n
    \r\n
    <p>The Greek scholar Archimedes found the solution.</p>\r\n
    \r\n
    <p>&ldquo;A body immersed in a fluid whether fully or partially immersed, is equal to the weight of the fluid that the body displaces&rdquo;</p>\r\n
    \r\n
    <p>Let&rsquo;s consider an example. When an object sinks in water, it displaces water.</p>\r\n
    \r\n
    <p>The volume of water displaced is equal to the immersed volume of the object.</p>\r\n
    \r\n
    <p>The bigger the object, the more water is displaced.</p>\r\n
    \r\n
    <p>Archimedes asserted that the weight of the volume of water displaced is exactly equal to the buoyant force except that this force goes upward.</p>\r\n
    \r\n
    <p>For buoyancy, the shape is as important as the mass</p>\r\n
    \r\n
    <p>A compact mass displaces very little water, whereas a ship, given its shape, displaces a lot of water.</p>\r\n
    \r\n
    <p>The greater the immersed volume, the greater the intensity of the buoyant force.</p>\r\n
    \r\n
    <p>Thus, a light object can sink whereas a very heavy object can float.</p>
