A machine is any man-made material structure with various moving parts that use energy to perform work. Machines are designed to reduce or replace the muscular or mental work of humans in accomplishing particular tasks. Simple machines include the lever, pulley, wheel and axle, wedge, and screw. Complex machines include clocks, computers, washers and dryers, refrigerators, and automobiles.
What else can I help you with?
What is the unit of weight in physics and how is it defined?
The unit of weight in physics is the Newton (N). It is defined as the force exerted on an object due to gravity.
Is a rolling ball a simple machine?
No, a rolling ball is not considered a simple machine. Simple machines are basic mechanical devices that help to make work easier, such as levers, pulleys, and inclined planes. A rolling ball does not fit the criteria of a simple machine as defined in physics.
How is work defined as the transfer of energy in the context of physics?
In physics, work is defined as the transfer of energy that occurs when a force is applied to an object and causes it to move in the direction of the force.
What is the unit for work and how is it defined in the context of physics?
The unit for work in physics is the joule (J). Work is defined as the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force.
What is the fundamental unit of charge and how is it defined in the context of physics?
The fundamental unit of charge is the elementary charge, denoted as e. In physics, it is defined as the charge of a single proton or electron, which is approximately 1.602 x 10-19 coulombs.

In physics work is defined as?
Force times distance
How is work defined as the transfer of energy in the context of physics?
In physics, work is defined as the transfer of energy that occurs when a force is applied to an object and causes it to move in the direction of the force.
Can you construct a Turing machine that accepts the language defined by the keyword?
A Turing machine can be built to accept the language defined by the keyword.
What is veloicity?
In physics, velocity is defined as the rate of change of position
What is the unit for work and how is it defined in the context of physics?
The unit for work in physics is the joule (J). Work is defined as the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force.
Will there there be a time machine?
In the Law of Physics, it is possible to have a time machine in the future, though you can not go back in time before the time machine was made.
Which of these terms is defined as the force applied to a machine?
resistence
Which terms defined as the force applied to a machine?
effort
How is astronomy defined?
Astronomy is a branch of physics investigating celestial bodies and phenomena.
Is there any black-hole on your earth?
No - at least no black holes as defined by physics.
