Lesson details
Key learning points
- Pressure can be calculated by dividing the force on the objects by the area on which the force acts.
- The units for force and area determine the units for pressure.
- By rearranging the formula, you can calculate either force or area.
Keywords
Pressure - Pressure is the perpendicular force applied to the surface of an object per unit area over which that force is distributed.
Force - A force is a push or a pull on an object. A force is an influence that can cause an object to change its speed.
Common misconception
Using the total surface area of the solid rather than the area of the solid that is in contact with the floor/table.
Refer back to the high-heeled shoe and elephants foot example. This should clarify that it is the area in contact with the foot that increases or decreases the pressure.
