The mechanical system that allows you to move and lift things is known as a simple machine. Examples include levers, pulleys, and ramps, which reduce the amount of force needed to lift or move objects. These systems work by altering the direction or magnitude of the applied force, making tasks easier and more efficient.
To move the body and use strength to lift things.
because it is the thing that allows you to move. Without it youm would not be able to do the most simplest things!!
allows you to move.
A lever allows you to magnify the force applied to an object at the expense of distance. With a lever you can move objects many times larger than you could without one, but at a slower pace.
A system that allows energy to move in and out but not mass.
A pulley system can change the direction of a force, making it easier to lift or move heavy objects. By distributing the force over multiple ropes and pulleys, it can also reduce the amount of force required to lift an object. This allows for more efficient use of energy in lifting objects.
You may be thinking of an "air foil", which also has the property of "lift" when oriented properly. See: http://en.wikipedia.org/wiki/Airfoil
muscles
It allows you to move your bones.
The musculeskeletal system is the organ system that allows a person to move using the muscular and skeletal system.
Muscles also help to move.
The force that helps us lift things is called muscular force, generated by our muscles contracting and producing tension to move an object against gravity.
