nothing is there
friction can cause the wearing away of surfaces
you can get pushed out of your orbit with enough force.
The disadvantage of an inclined plane is you need a greater force.
Force is a push or pull on an object resulting from its interaction with another object. There are four main types of force: gravitational force, electromagnetic force, weak nuclear force, and strong nuclear force. Advantages of force include the ability to move objects, cause changes in motion, and create interactions between objects. Disadvantages of force can lead to damage, injury, or destruction if not properly controlled or applied.
Max forging force is not as high as screw or hydraulic presses.
If the ramp is steep you will need more force to push it.
if there is a power cut than they will jam shut and you have to force them open
Friction is a force that must be overcome for no useful purpose. It takes energy to do this, and thus is wasteful.
disadvantage of first class the fulcrum lies on more effort or more force.
Advantages of magnetic force include its ability to create electricity through electromagnetic induction and its use in various technologies like MRI machines and compasses. Disadvantages may include interference with electronic devices and the potential health risks associated with strong magnetic fields.
Your load could slow down depending on how much force applied.
