FAQs on Class 8 Science - Force and Pressure CBSE Worksheets

1. What is the difference between force and pressure?
Ans.Force is a push or pull acting upon an object, measured in newtons (N), while pressure is the force applied per unit area, measured in pascals (Pa). Pressure indicates how concentrated the force is over a surface.
2. How is pressure calculated?
Ans.Pressure is calculated using the formula: Pressure (P) = Force (F) / Area (A). This means you divide the total force applied to a surface by the area over which the force is distributed.
3. Why is pressure important in everyday life?
Ans.Pressure is crucial in various everyday applications, such as in tires, where proper pressure ensures safety and efficiency; in hydraulics, where it enables machinery to lift heavy loads; and in cooking, where pressure cookers speed up the cooking process.
4. What units are used to measure force and pressure?
Ans.Force is measured in newtons (N), while pressure is measured in pascals (Pa). One pascal is defined as one newton of force applied over an area of one square meter.
5. How does altitude affect atmospheric pressure?
Ans.Atmospheric pressure decreases with altitude because there is less air above exerting pressure. As you climb higher, the air becomes thinner, leading to lower pressure. This is why mountain climbers often experience difficulties due to reduced oxygen availability.
