Forces
- Weight and Mass
- Mass
- This is a measure of how much matter there is in an object
- It is measured in Kg
- Mass is constant
- Weight
- WEight is measured in N
- WEight is the force gravity
exerts on an object
- The weight of an object
changes from place to place
- Weight = Mass x gravity
- Density
- Density = Mass/Volume
- Kg/M^3
- Measuring and Drawing Forces
- Forces are measured in N
- We can measure forces using a Newton Meter
- The larger the force the more the spring extends
- Drawing Forces
- The larger the arrow the
larger the force
- Balanced And Unblanced Forces
- Balanced
- The object will remain stationary
- The object will carry on moving at a steady speed
- Unbalanced
- The object may speed up
- Slow down
- Stop moving
- Start moving
- Change direction
