What is a Machine in Physics
Define Machine in Physics
A machine is a device by means of which useful work can be performed conveniently and it can also transfer one form of energy into another form of energy.
The ratio between the resistance or weight to the power applied in a machine is called the mechanical advantage of that machine. It is denoted by MA.
- = Weight over-come by Machine/ Force Applied on the Machine
The ratio between the useful work done and the work done on the machine is called efficiency.
MA = (output/Input) * 100
Input is the work done on the machine.
Output is useful work clone by the machine.
And with us, as a rule, first they learn to dig the ground with their hands, and only then they think how to get a good shovel or even a tractor. Likewise, in education, the methodology of cognition is often put on the background. Few people teach to learn.Moreover, educational institutions hardly speak to the proper extent about the subtleties, nuances of the perception of information, the use of modern technologies.
