Pressure

1. Important forces

1.1. Frictional Force ( Friction )

1.2. Magnetic Force

1.3. Gravitational Force ( Gravity )

2. Increasing Pressure

2.1. Force needs to be applied to a smaller surface area.

3. Decreasing Pressure

3.1. Force needs to be applied to a larger surface area.

4. What is Pressure

4.1. Pressure is the amount of force acting per unit area.

5. Calculating pressure

5.1. Force / Area

6. Effects of forces

6.1. Change the direction of motion of an object

6.2. Cause a stationary object to move

6.3. Stop or slow down a moving object

6.4. Change the physical form of an object

7. What is a force?

7.1. A force is a push or pull, the capacity to do work or cause physical change.

8. Measuring force

8.1. Multiply the mass of that object by its accelaration to calculate its force
