as he walks at a steady pace across a room, might think he's working hard. (He might even be perspiring.) But, by definition, he is not doinganywork. True, the waiter is using force to push the tray above his head, and also true, the tray is moving across the room as the wa...
What is physics? Is physics science? Learn the definition of physics and the relation between physics and science. See the various branches of...
In physics, one way to distinguish between mass and matter is to define matter as a substance consisting of particles that exhibit rest mass. Even so, in physics and chemistry, matter exhibits wave-particle duality, so it has properties of both waves and particles....
Joule (J) is the SI unit of work. A joule is defined as the work used by a force of one newton through a displacement of a metre. Given here is the table of units along with the dimensional formula.

What is the unit of work? Work: Work is a quantity in physics that deals with moving an object a specific distance. If a force is applied to an object and it doesn't move, no work is done on the object. Positive and negative work can be done by a force. Answer and Explanation: ...
Other definitions of Physics states, "It is the study of natural science that studies the related entities of force and energy, motion and behavior of an object through space and time, matter and its fundamental constituents." In simple words, it can be said that physics is one of the most...
The concept of work in physics is much more narrowly defined than the common use of the word. Work is done on an object when an applied force moves it through a
What is specific gravity? What is the definition of gravity? Define gravity. What does gravity actually pull? What causes Gravity? How do you define gravity? What is mean by the specific gravity? What would be the basic theory to reverse gravity? Explain needed so basically using gravity to...
If foundations are not well laid down, the building is going to be fragile. This idea of a precise mathematical coordinateless definition for spacetime is something that is floating around in my mind since a few years, and now and again I've been looking for a similar approach. Until I ...
