pressure

1. unit for pressure - N/m2 or N/cm2 or Pascal (Pa)

2. decreasing/reducing pressure

2.1. we reduce pressure by increasing the are ij contact

3. pressure increases when...

3.1. force increases

3.2. area decreases

4. what is pressure

4.1. calculating pressure-Force/area= pressure

4.2. depends on 2 factors: force and area

4.3. it is the force exerted per unit area

5. increasing pressure

5.1. we increase pressure by decreasing the area in contact
