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.

FranMachines can make work easier by transferring energy from one form to another with higher efficiency than manual labor. They do not violate the law of energy conservation because they simply convert energy from one form to another, without creating or destroying energy. This allows machines to perform tasks more effectively and with less effort compared to humans.

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.
