What is the concept of energy balance?
(EH-ner-jee BA-lunts) In biology, the state at which the number of calories eaten equals the number of calories used. Energy balance is affected by physical activity, body size, amount of body fat and muscle, and genetics.
What is the energy equation GCSE PE?
To calculate how much energy the body needs, the following equation may be used: Basal metabolic rate (BMR) + physical activity level (PAL) = total energy requirement.
What is energy balance in thermodynamics?
The balance is expressed in words as: all energies into the system are equal to all energies leaving the system plus the change in storage of energies within the system.
What is energy balance equation in electrical machine?
dWmech = Change in mechanical energy. dWf = Change in field energy. dWloss = Change in energy losses. The transferred energy are always taken as positive ( + Ve ) but change in stored energy in the coupling field may be either positive or negative in the energy balance equation.
What is energy balance in nutrition PDF?
“Energy balance” is the relationship between “energy in” (food calories taken into the body through food and drink) and “energy out” (calories being used in the body for our daily energy requirements).
What is mechanical energy balance?
The mechanical energy balance is a type of energy balance that can tell us a great deal about simple flow systems. We begin with a discussion of conservation of energy and derive the mechanical energy balance (MEB). Finally, we show how to apply the MEB to simple flow systems.
What does energy equation mean?
The energy equation is the mathematical formulation of the law of conservation of energy.
How does Earth’s energy balance work?
The earth-atmosphere energy balance is achieved as the energy received from the Sun balances the energy lost by the Earth back into space. In this way, the Earth maintains a stable average temperature and therefore a stable climate.
How do greenhouse gases affect the energy balance of Earth?
Increases in the concentrations of greenhouse gases will reduce the efficiency with which the Earth’s surface radiates to space. More of the outgoing terrestrial radiation from the surface is absorbed by the atmosphere and re-emitted at higher altitudes and lower temperatures.
