My pressure map

1. Friction can be reduced by using smooth surfaces, ball bearings, lubrication or by streamlining

2. Friction can slow down and stops a moving object. Friction produces heat. Friction helps us to hold things. Friction between our feet and ground gives us the grip to walk or run.

3. what are the most IMPT forces? Frictional, magentic and gravitational

4. A forsce is a pull or a push applied to an object

5. How do we calculate pressure?

6. Measuring force

6.1. Using a spring balance

6.2. The spring balance is brokan into two parts

6.3. Extension

7. The force that pulls objects towards the earth is called a gravitational force.

8. Weight is not equal to mass

9. Calculating pressure: force/area
