Schedule: Pressure Notes (ISN 59) Pressure Math (ISN 61) Objective: (ISN 59) I can understand what pressure is and how amount of force and area affects it. (ISN 60) I can understand how to calculate pressure Homework Bring Pennies Finish Pressure Math Please have on desk: 12.3 RSG

Pressure depends on area The amount of pressure we feel depends on how much force is applied over how much area P = F/A

Pressure acts in all Fluids Liquids and gases exert pressure in all directions on the things around them. Why don’t we notice that the air around us is pressing on us?

Pressure acts in all Fluids For every action, there is an equal an opposite reaction. Air pushes on us, we push on air with an equal, but opposite force. (Newton was brilliant!)

Pressure acts in all Fluids Ears hurt when pressure outside is greater than pressure inside. Ears hurt when pressure inside is greater than pressure outside

Air Pressure decreases as you climb higher in the atmosphere Pressure acts in all Fluids As you climb less air is above you. Less Force = Less Pressure

Pressure acts in all Fluids Water Pressure increases as you dive deeper More water is above you, so it exerts a greater Force on a given Area. More Force = More Pressure

What is the purpose of wearing snow shoes?

6/14/2016Free template from 10 Possible Answer The lady wants to spread her force out over a larger area of the snow so she stays on top of it. If she did not have snowshoes, she might “sink” into the snow. If her force is spread out, there is not enough pressure on any one spot to “sink”.

Free template from Why doesn’t the person on the bed of nails get pierced by them?

Possible answer The force of the nails on the person’s body is spread out over the area of his entire body. No one nail has enough pressure to pierce the skin.

Wednesday, March 16 th Entry Task 1.What is the formula for pressure? 2.The higher in the atmosphere you go the __________ the air pressure gets. 3.If something is more dense it has more/less (choose one) pressure. 4.What is the unit for pressure? 5.Explain pressure differences in water, use force in answering Schedule: 12.4 Buoyancy (ISN 63) Homework: Bring Pennies BY TOMORROW!! Read/RSG 12.4 (ISN 63) Objective: (ISN 63)I can understand that fluids can exert a force on objects Please Have on Desk: Pressure Math

Buoyant force It is the upward force on objects in a fluid Why ice floats in water Objects seem lighter in water Buoyant forces on an object are equal to the weight of the water that is displaced by the object If an object is more dense than the fluid then it will have a less buoyant force and sink.

Motion of fluid affects pressure Bernoulli’s principle –An increase in the speed o the motion of a fluid decreases the pressure within the fluid –The faster a fluid moves, the less pressure it exerts on the surfaces of openings it flows over. –Chimney, air plane, race car and prairie dog examples

Forces transmitted through fluids Pascal’s Principle –When an outside pressure is applied at any point to a fluid in a container, that pressure is transmitted throughout the fluid with equal strength.
