Unit 3: Motion, Forces, & Energy Chapter 11: Motion & Energy Big Idea: If an object is less dense than a fluid, it will float in the fluid. If an object is more dense than a fluid, it will sink in the fluid Mrs. Lee - Ch 11
4 Sections 1. 2. 3. 4. Pressure Floating & Sinking Pascal’s Principle Bernoulli’s Principle Mrs. Lee - Ch 11 2
Sec 1: Pressure KEY CONCEPTS • The amount of pressure you exert depends on the area over which you exert a force • Pressure = Force Area • In a fluid, all of the forces exerted by the individual particles combine to make up the pressure exerted by the fluid Mrs. Lee - Ch 11 3
Sec 1: Pressure (cont’d) • Atmospheric pressure decreases as your elevation increases • Water pressure increases as depth increases Mrs. Lee - Ch 11 4
Sec 1: Key Terms • • Pressure Pascal Fluid Barometer Mrs. Lee - Ch 11 5
Sec 2: Floating & Sinking KEY CONCEPTS • Density = Mass Volume • By comparing densities, you can predict whether an object will float or sink in a fluid • The buoyant force acts in the direction opposite to the force of gravity, so it makes an object feel lighter Mrs. Lee - Ch 11 6
Sec 2: Key Terms • Density • Buoyant force • Archimedes’ principle Mrs. Lee - Ch 11 7
Sec 3: Pascal’s Principle KEY CONCEPTS • When force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid • A hydraulic system multiplies force by applying the force to a small surface area. The increase in pressure is then transmitted to another part of the confined fluid, which pushes on a larger surface area Mrs. Lee - Ch 11 8
Sec 3: Key Terms • Pascal’s principle • Hydraulic system Mrs. Lee - Ch 11 9
Sec 4: Bernoulli’s Principle KEY CONCEPTS • Bernoulli’s principle states that as the speed of a moving fluid increases, the pressure exerted by the fluid decreases • Bernoulli’s principle helps explain how planes fly. It also helps explain how an atomizer works, why smoke rises up a chimney, & how a flying disk glides through the air Mrs. Lee - Ch 11 10
Sec 4: Key Terms • Bernoulli’s principle • Lift Mrs. Lee - Ch 11 11
