Force and Pressure
저자: ONG YU YUAN SHEILA .
1. Pressure
1.1. Pressure is the amount of force that is exerted on the surface of an object per unit area .
1.2. Pressure=Force/Area
1.3. We can increase pressure by reducing the area of an object.
1.4. We can reduce pressure by increasing the area of an object.
2. Force
2.1. Force is a push or a pull
2.2. Effects of force
2.2.1. Change in direction
2.2.2. Change in shape
2.2.3. Change in speed
2.2.3.1. Faster
2.2.3.2. Slower
2.2.4. Stop an object from moving
2.2.5. Make an object start moving
2.3. Measuring force
2.3.1. It can be measured by a spring balance.
2.3.2. It can also be measured by a compression balance.
2.3.3. Force=MassXAcceleration Shortcut: F=MA
