What is the definition of work in physics? Work is a quantitative scalar property that is equal to the dot product of the force acting on an object and the displacement of an object. It has the units of Joules, which is equivalent to Newton-meters. Work can be positive, negative, or ...

Examples of scalars are volume, density, speed, energy, mass, and time. Other quantities, such as force and velocity, have both magnitude and direction and are called vectors. Scalars are described by real numbers that are usually but not necessarily positive. The work done on a particle by...

The concept of voltage, like those of charge and current, is fundamental to the science of electricity. Voltage is a measure of thepropensityof charge to flow from one place to another; positive charges generally tend to move from a region of high voltage to a region of lower voltage. A...

Definition of Period The period T of a wave might not be a term you're familiar with if you haven't studied physics before, but its definition is still quite straightforward. The period of the wave is the time it takes for one oscillation to take place, or for ...

In the language of physics, "positive work" and "negative work" are sometimes being used. A positive work (+W) means that the object's kinetic energy increases, which means it is speeding up because of the force applied. If the kinetic energy decreases, negative work (-W) is done, ...
Kinetic energy is the energy of a body's motion. It ranges from 0 to a positive value. Example: An example is a child swinging on a swing. No matter whether the swing is moving forward or backward, the value of the kinetic energy is never negative. ...
