For example, a lever can help you require less force. Force is not energy. To lift up (for example) a car, with a lever, you may need to apply less force than the weight of the car, but over a greater distance. Work is force x distance, and the amount of work - which is basically the mechanical energy required to move it - doesn't change.

What machines that create unusable energy?
Perpetual motion machines are theoretical machines that aim to create unlimited energy without an external source but violate the laws of thermodynamics, making them impossible to create in reality. Other examples of machines that create unusable energy could include inefficient or poorly designed machines that waste energy in the form of heat, noise, or other non-usable forms.
What energy produced by machines?
Machines produce mechanical energy through the movement of their parts, and electrical energy when powered by electricity. Some machines also generate thermal energy through processes like combustion or friction. Overall, machines convert one form of energy into another to perform tasks.
How is energy needed to make machine work?
Energy is needed to make machines work because it powers the movement and function of the various components within the machine. This energy can come from sources such as electricity, fuel, or human input, and is converted into the mechanical energy needed to operate the machine. Without energy, machines would not be able to function and perform their intended tasks.
What is the difference between perpetual motion machines of first kind and perpetual motion machines of the second kind?
Perpetual motion machines of the first kind are hypothetical machines that violate the first or second law of thermodynamics by producing energy without any external source. Perpetual motion machines of the second kind are also hypothetical, but they generate energy by utilizing an external source and converting some of it into work without depleting the source. Both types of machines are not possible based on our current understanding of physics.
Can machines increase energy?
Machines themselves cannot inherently create energy; they can only convert energy from one form to another. Machines can be used to harness energy from different sources such as fossil fuels, wind, or solar power, but they cannot create energy on their own.
Explain how machines can make work easier without violating the law of conservation of energy?
A simple machine will increase the total time effort must be exerted and decrease the amount of effort required in any given second. The law of conservation of energy still holds because it still take the same amount of energy to get the job done.
When do you use muscular energy?
to do work with or without the help of machines.
Why do living things and machines need energy?
living things need energy because they cannot live longer without energy

Locating facilities so that energy consumption will be minized without violating the concepts of functional grouping and dispersal is best associated with?
Solar Orientation
What are hypothetical machines?
A simple machine that can produce energy without using any fuel to operate.
How do machines create energy?
It is wrong to say machines create energy. Machines have to be given energy to make them effective. This could be electric energy, solid liquid or gaseous energy, thermal energy, mechanical energy (like a flywheel for example). It may be possible to design machines which will search for their energy by themselves, some robots may already have achieved. Remember we humans are also machines, but we get our energy from digesting food.

How machines make work easier?
Simple machines using pulleys and levers, make the work easier by using mechanical advantage. The input force is less than the output, but spead over a larger distance and time. Other machines harness engines and motors, to take over the human input. The motors and engines need a separate source of energy.
What do simple machines do to make work easier?
Simple machines make work easier by reducing the amount of force needed to perform tasks or by changing the direction of the applied force. They achieve this by increasing the distance over which the force is applied or by allowing for a more efficient transfer of energy. Examples include levers, pulleys, and inclined planes, which can multiply force or allow for easier movement of heavy objects. By simplifying tasks, simple machines enhance efficiency and reduce effort.

What does mechanical energy do?
It is an energy that is done through machines.
