Forces and Pressure

1. A force is either a push or a pull.

1.1. New node

2. The formula for force is mass times 10N,which is the gravitational pull of the earth.

3. Pressure is the force acting per unit area

4. Pressure increases when the force increases or the contact area decreases.

5. The formula for calculating pressure is force divide the contact area.

6. The SI unit for pressure is : Pascal

7. Effects of forces are : A force can make a stationary object start moving. The distance moved by an object depends on the force applied on the object. If a larger force is applied, the object will move a greater distance. A force can change the shape of an object.

8. A force can make a moving object: Move faster Move slower Change its direction of movement Stop moving A force can change the shape of a moving object as a force can have high impact or low impact on the object it is applied to.
