## 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.
