pressure

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

2. what is pressure

2.1. calculating pressure-Force/area= pressure

2.2. depends on 2 factors: force and area

2.3. it is the force exerted per unit area

3. increasing pressure

3.1. we increase pressure by decreasing the area in contact

4. decreasing/reducing pressure

4.1. we reduce pressure by increasing the are ij contact

5. pressure increases when...

5.1. force increases

5.2. area decreases
