In the real world, machines are never 100% efficient. There is always loss of energy, usually due to friction.
By contrast, in physics problems, an "ideal machine" is a hypothetical device which is perfectly efficient. The assumption of perfect efficiency allows the problem to focus on the fundamental mechanical principles.
What else can I help you with?
Do machines in the real world lose energy due to friction?
Yes, machines in the real world lose energy due to friction. Friction causes resistance, which leads to heat generation and energy loss. This energy loss can affect the efficiency and performance of machines.
Which is true of all simple machines?
All simple machines change the direction or magnitude of a force to make work easier. They operate on a basic mechanical principle and do not have moving parts. Simple machines can be combined to create more complex machines.
What applies to a real machine?
A real machine is a physical device that performs mechanical tasks in the physical world. It operates based on principles of physics and mechanics to convert inputs into outputs. Examples include cars, washing machines, and computers.
What statements about physical models is not true?
One statement that is not true about physical models is that they are always exact representations of the real-world system. Physical models are simplifications of real-world systems and may not capture every detail or aspect of the system. Additionally, physical models are subject to limitations in terms of accuracy and applicability.
How are electromagnets used in the real world?
Electromagnets are used in various real-world applications such as MRI machines in medicine, maglev trains for transportation, and in industrial settings for lifting and separating metal objects. They are also used in speakers, electric motors, and generators.
What is always true about machines in the real world?
They always eventually break.
What is tool and technology?
machines that may be used to solve real-world problems
Are time machines?
are time machines real
Geometry can applied to real world probelm?
true
Do machines in the real world lose energy due to friction?
Yes, machines in the real world lose energy due to friction. Friction causes resistance, which leads to heat generation and energy loss. This energy loss can affect the efficiency and performance of machines.
Is it true that geometry can be applied to real world problems?
Yes
