## Study Notes

### Simple Machines

• An inclined plane is used to lift heavy loads with less effort by distributing the weight over a longer distance, making it easier to move.
• In simple machines, the relationship between effort and load is that the effort is reduced while the load remains the same, allowing for easier lifting or movement.
• A fixed single pulley changes the direction of force by reversing it, allowing the effort to be applied in a more convenient direction.
• The key function of simple machines like pulleys, wheels, levers, wedges, and screws is to make work easier by changing the direction or magnitude of the force applied.
• Simple machines are considered force multipliers because they allow a small effort to move a larger load.
• The purpose of simple machines is to make work easier by reducing the effort required to lift or move heavy loads.
• Simple machines change the direction of force by redirecting the effort, making it easier to lift or move heavy loads.
• Using an inclined plane to move a heavy box to the second floor of a building is easier because it distributes the weight over a longer distance, reducing the effort required.
• Simple machines affect the strength of a force applied by reducing the effort required, making it easier to lift or move heavy loads.
• For simple machines to function effectively, the mechanical advantage must be greater than one, meaning the output force must be greater than the input force.
