Systems in Action Terms: Flashcard Set
System: A group of parts that work together to achieve a certain goal.
Physical System: A group of physical parts that work together to perform a specific function.
Social System: A group of humans or other organisms joining together to perform tasks or form relationships.
Force: Any push or pull.
Input: The force, energy or raw materials put into a system.
Output: The task or purpose that a system performs.
Side Effects: The unintended or undesired outputs of a system.
Systems Thinking: Taking into account the inputs ,outputs or side effects of a system.
Simple machine: a device that requires a single force to work.
Fulcrum: the pivot of a lever.
Load arm: the part that extends to the load.
Effort arm: The part of a lever that extends to where the pressure is applied from.
Input force: the effort force applied to a lever.
Output force: The force the lever applies to the load.
Load force: The force the input force has to overcome to cause any movement.
Inclined plane: For the moving of heavy objects vertical with ease.
Wedge: Used to stop the movement of a machine.
The screw: Used to drill through materials or to move liquid materials.
The lever Used to move a load( usually heavy) with ease.
Wheel and axle: Used to transfer small force into big actions, change types of force.
The pulley: Used to lift heavy objects with ease.
Scientific terms | Common terms and expressions |
Gravitational force | Pull of Earth |
Magnetic force | Magnetic pull/push |
Electrical force | Static ,electrical current’s force ,force of lightning |
Mechanical force | Muscular force |
Frictional force | Rubbing ,abrasion |
Tensile force | tightening |
Compressive force | Crush ,squash |
Rotational force | Spin ,twist |
Magnitude: the quantity of force
Newton: the unit used to measure forces (N)
Friction: the force that resists objects rubbing or sliding past one another.
Static friction: The force that holds a motionless object where it is
Sliding friction: The force that acts like a brake one one surface slides over another
Lubricant: a substance that reduces friction
Mechanical advantage (MA): the ratio of output force to input force of a given machine
Ideal Mechanical advantage: the MA if all output force was converted to input force, not possible in real world applications.
Actual Mechanical advantage: The MA in real applications ,equal to the ideal MA minus the force lost to friction ,slippage ,etc.
