    Progressive loss of total bone mass. Possible causes are physical inactivity, hormonal changes, and increased osteoclasts activity. The effect is weaker bones, causing vertebrates to be softer and long shaft bones to be less resistant to bending. Walk slower, take smaller steps, appear less coordinated. Decreases their base of support.   this video describes Physical & Chemical Changes in matter. Intro to Chemistry, Basic Concepts - Periodic Table, Elements, Metric System & Unit Conversion - .

      Physical properties change during physical change. For example, color, shape, size, volume, durability. Examples: Melting of ice Breaking of wire into pieces. Dissolving sugar in water. Freezing water to make ice. Cutting paper into pieces. Chemical changes. During chemical change a new substance is formed. The composition of a substance.   A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Often, physical changes can be undone, if energy is input.
