Forces and Balancing
- When forces are balanced the object won't move.
- If the forces are unbalanced then the object will move which ever way the weakest force
is.
- Levers
- Magnify the 'effort' (force which is applying the pressure)
- Turns objects around pivots.
- Load is the object which is being lifted
- Magnets
- The same poles repel
- Opposite poles attract
- Some metals are magnetic - they
attract magnetic materials, Iron, Nickel
and Cobalt are some examples.
- Pressure
- The smaller the area of an object, the higher the pressure.
- When more force is applied then the pressure increases.
- If a pin was pressing in to your hand and a hammer was pressing
into your hand with the same force, the pin would pierce your skin
and be more painful. The hammer would not hurt much.
