Work input equals work output is what type of machine?
A machine that has work input equal to work output is known as an ideal machine. This means that the machine is 100% efficient, converting all the input work into useful output work without any losses. Ideal machines only exist in theory, as real machines always have some energy losses due to factors like friction and heat.
What is a real life example of acceleration?
A car speeding up from a stop sign is a real life example of acceleration. As the driver presses on the gas pedal, the car's velocity increases over time, showing acceleration.
Can we literally go back in time with a time machine?
The concept of time travel to the past is currently not supported by any empirical evidence or scientific theory. It remains a topic of speculation and fiction in the realm of physics. The laws of physics as we currently understand them do not provide a method for traveling back in time.
When is the time machine really going to be maded?
There is currently no concrete evidence or scientific breakthroughs indicating the development of a functional time machine. The concept of time travel remains theoretical and is not a reality as of now.
What is the efficiency of a machine that miraculously converts all the input energy to useful output energy?
The efficiency of such a machine would be 100%, as all the input energy is converted to useful output energy without any losses. This would be an ideal scenario but is not practically achievable due to factors such as friction, heat dissipation, and other forms of energy loss in real-world machines.
