Who defined work? In physics, work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force. What is the classic definition of work? Work is physical or mental […]

Is mass equal to weight?
Is mass equal to weight? In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on […]

Why is nitrogen so cold?
Why is nitrogen so cold? Liquid nitrogen is so cold because of the way molecules change as a gas turns to liquid. Nitrogen doesn’t naturally occur in a liquid form here on Earth. This compression causes the gas to heat up. While keeping the pressure high we cool it down to the temperature of the […]
