Forces and fluids
Текст на Статията
- Class take a seat we will be starting our new unit in science today called forces and fluids.
- ok
- The first thing we will disscus is viscosity, does anyone know what it is?
- And when you increase the temperature you will decrease the viscosity and when you decrease the temperature you will increase the viscosity it is a inverse relationship.
- Viscosity is a liquids internal resistance or friction that keeps it from flowing.
- Very well, ok so we know that buoyancy is the tendency to rise or float in water or air but what our some examples of buoyancy in our everyday life?
- Very well maggie.
- An examples would be when boats, ships and submarine float in water.
- Kyi can you please repeat what Maggie just said? Please pay attention
- Umm no what happened?
- Yes because honey has a higher viscosity then water
- Is viscosity the reason water flows faster then honey?
- Im so board
- Bouancy Bouyancy is the tendency to rise or float in water or air
- A objest will either float or sink depending on its density.
