Pressure

Pressure is the force applied perpendicular to the surface of an object per unit area. It is a measure of how much force is acting on a certain area.

Formula for Pressure:

The formula for pressure is:

Pressure = Force / Area

Units of Pressure:

The SI unit of pressure is the Pascal (Pa), which is equal to one Newton per square meter (N/m²).

Other common units of pressure include atmospheres (atm), millimeters of mercury (mmHg), and pounds per square inch (psi).

Factors Affecting Pressure:

The pressure exerted by a force depends on the magnitude of the force and the area over which the force is distributed. Increasing the force or decreasing the area will increase the pressure, and vice versa.

Applications of Pressure:

Pressure is involved in various real-life applications, such as hydraulic systems, pneumatic systems, and the functioning of tools like hydraulic jacks and car brakes.

Multiplication

The resources above cover the following skills:

Number and Operations (NCTM)

Compute fluently and make reasonable estimates.

Develop fluency in adding, subtracting, multiplying, and dividing whole numbers.

Select appropriate methods and tools for computing with whole numbers from among mental computation, estimation, calculators, and paper and pencil according to the context and nature of the computation and use the selected method or tools.

Algebra (NCTM)

Use mathematical models to represent and understand quantitative relationships.

Model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions.

Connections to the Grade 5 Focal Points (NCTM)

Number and Operations: Building on their work in grade 4, students extend their understanding of place value to numbers through millions and millionths in various contexts. They apply what they know about multiplication of whole numbers to larger numbers. Students also explore contexts that they can describe with negative numbers (e.g., situations of owing money or measuring elevations above and below sea level).
