๐Ÿ“š Quick Study Guide

  • ๐Ÿ’ง Density: ๐Ÿงช Density is how much 'stuff' is packed into a certain space. Think of it as how heavy something is for its size.
  • โš–๏ธ Buoyancy: ๐ŸŒŠ Buoyancy is the upward force that a fluid (like water) exerts on an object. If the buoyant force is greater than the object's weight, it floats!
  • ๐Ÿงฎ Density Formula: ๐Ÿ“ Density is calculated as: $Density = \frac{Mass}{Volume}$
  • ๐ŸŽ Floating vs. Sinking: ๐Ÿšข If an object is less dense than water, it floats. If it's more dense, it sinks. Think of a light apple floating versus a heavy rock sinking.
  • โœจ Factors Affecting Buoyancy: ๐ŸงŠ The shape of an object can also affect whether it floats or sinks. Even steel can float if shaped into a boat!
