## What is the definition of energy equation?

The energy equation is the mathematical formulation of the law of conservation of energy.

What is energy equation in thermodynamics?

The first law of thermodynamics is given as ΔU = Q − W, where ΔU is the change in internal energy of a system, Q is the net heat transfer (the sum of all heat transfer into and out of the system), and W is the net work done (the sum of all work done on or by the system).

### What is the work-energy equation?

Mathematically, work is W = F · x, where F is the applied force and x is the distance moved, that is, displacement. Work is a scalar. The SI unit for work is the joule (J), which is newton‐meter or kg m/s 2. If work is done by a varying force, the above equation cannot be used.

What is Q energy equation?

where Q is the quantity of heat transferred to or from the object, m is the mass of the object, C is the specific heat capacity of the material the object is composed of, and ΔT is the resulting temperature change of the object.

#### What is total energy?

Total Energy is the total final energy consumption at a specific branch/variable. Total energy is distinguishable from Final Energy Intensity by the fact that energy data is entered directly: that is it is not specified as the product of an activity level and an energy intensity.

What is total energy physics?

The total energy of a system is the sum of kinetic and gravitational potential energy, and this total energy is conserved in orbital motion. Objects must have a minimum velocity, the escape velocity, to leave a planet and not return.

## What is work-energy theorem and prove it?

Work energy theorem states that the work done by the net force acting on a body is equal to the change produced in the kinetic energy of the body. Δ W = F ( x ) Δ x.

Why is the work-energy theorem important?

Though the full applicability of the Work-Energy theorem cannot be seen until we study the conservation of energy, we can use the theorem now to calculate the velocity of a particle given a known force at any position. This capability is useful, since it relates our derived concept of work back to simple kinematics.
