What is GZ in thermodynamics?

What is GZ in thermodynamics?

Thus, the right side of the above equation can be called the General Integral Equation for Conservation of Energy in a Control Volume, where e = total energy of the fluid per unit mass, , = internal energy per unit mass, = kinetic energy per unit mass, gz = potential energy per unit mass.

What is the best example of potential energy?

An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy.

Is a potential energy?

Potential energy is the energy stored within an object, due to the object’s position, arrangement or state. Potential energy is one of the two main forms of energy, along with kinetic energy.

What is the formula of potential energy Class 9?

The potential energy (Ep) is equal to the work done over an object of mass ‘m’ to raise it by a height ‘h’. Thus, Ep = mgh, where g = acceleration due to gravity.

What is energy class 9th?

Energy is defined as the ability to do work. SI unit of energy or work = Joule (Nm) or Kgm2s−2. Energy has different forms: Light, heat, chemical, electrical or mechanical.

What are the 7 types of potential energy?

Systems of objects ranging from atoms to planets can be arranged in many ways, resulting in many forms of potential energy: chemical, elastic, electrical (electromagnetic), gravitational, nuclear, and thermal energy.

What are the 4 types of kinetic energy?

There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical. Let us look at some of the kinetic energy examples and learn more about the different types of kinetic energy.

What are 6 forms of potential energy?

Energy comes in six basic forms: chemical, electrical, radiant, mechanical, thermal and nuclear. In other research, you may find additional forms mentioned such as electrochemical, sound, electromagnetic and others. However, many additional forms are combinations of these six basic categories.

What are the 3 factors that affect potential energy?

Gravitational Potential Energy is determined by three factors: mass, gravity, and height. All three factors are directly proportional to energy.

What factors that affect potential energy?

The factors that affect an object’s gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in.

What are examples of potential energy in your home?

By keeping in mind all the above information about the potential energy, let us now look at some examples of potential energy from everyday life.

• Pendulum.
• Spring.
• Bow & Arrow.
• Rock At Cliff’s Edge.
• Food We Eat.
• Water In Dams & Reservoirs.
• Snow.
• Bullet.

What is the mechanical energy of an object?

The energy of an object due to its motion or position; the sum of an object’s kinetic energy and potential energy.

What are two types of mechanical energy?

There are two main types of mechanical energy. They are motion energy and stored mechanical energy. Motion energy: This is the energy something has because it is moving (eg a speeding cricket ball). You can feel the effect of this energy if the cricket ball hits you.

What is the main source of mechanical energy?

Mechanical Energy Kinetic energy is motion. The faster an object moves, the higher its kinetic energy. The energy of rivers (hydraulic energy) and of the wind (wind energy.

What is an example of mechanical energy to heat energy?

Rubbing your hands together converts mechanical energy to thermal energy. Turning on a light switch converts mechanical energy to electrical and radiant energy. Digesting food converts mechanical energy to chemical energy.

Does a battery have mechanical energy?

First, the definition of a battery must be established. There are a variety of chemical and mechanical devices that are called batteries, although they operate on different physical principles. There are no batteries that actually store electrical energy; all batteries store energy in some other form.
