GCSE Secondary Maths Age 13-17 - Ratio, Proportion & Rates of Change: Force - Explained

The video tutorial explains how to calculate pressure using the formula pressure equals force divided by area. It involves converting the area from centimeters squared to meters squared, a common point of confusion for students. The tutorial provides a step-by-step calculation of pressure exerted by a force of 900 newtons on an area of 60 centimeters squared, resulting in 150,000 newtons per meter squared. The video emphasizes the importance of unit conversion and offers tips to avoid common mistakes.

What is the formula for calculating pressure?

• Pressure = Force / Area

• Pressure = Force * Area

• Pressure = Area / Volume

• Pressure = Area / Force

How many square centimeters are there in one square meter?

• 10,000

• 100

• 1,000

• 100,000

Why is it important to convert 60 cm² to m² in this problem?

• To make the numbers smaller

• To match the units required for the answer

• To avoid using a calculator

• To simplify the calculation

What is a common mistake students make when converting cm² to m²?

• Dividing by 100 instead of 10,000

• Forgetting to multiply by 100

• Using the wrong formula for area

• Multiplying by 1,000

What is the final pressure exerted by a force of 900 newtons on an area of 60 cm², converted to m²?

• 15,000 newtons per meter squared

• 150,000 newtons per meter squared

• 1,500 newtons per meter squared

• 15 newtons per meter squared
