Energy

The electrical energy from the audio signal is transformed into mechanical energy as the speaker cones vibrate. This mechanical energy then creates sound waves in the surrounding air, which we perceive as sound.

Photovoltaics convert light energy from the sun into electrical energy through the photovoltaic effect, which involves the generation of an electric current when sunlight interacts with a semiconductor material.

At a receiving station, electrical energy is transformed from high voltage to lower voltage levels using transformers, allowing for efficient distribution through power lines. This transformation reduces energy losses and ensures that the electricity is at a safe and usable level for consumers.

When energy changes form, some energy is not converted into the desired form and is lost as waste heat. This is known as energy inefficiency and is a common occurrence in many energy conversion processes. One way to minimize energy loss is through improved energy efficiency technologies and practices.

The human body converts food into energy through a process called cellular respiration. During this process, glucose and oxygen are combined to produce ATP, which is the energy currency of the cells. The energy stored in ATP is used for various activities of the body, such as movement, growth, and maintenance of body temperature.

The sound of a cymbal is a form of mechanical energy produced by the collision of the two metal plates creating vibrations in the air molecules, which we perceive as sound.

Chemical energy is a form of potential energy stored in the bonds of chemicals. When these bonds are broken, the potential energy is converted into other forms of energy, such as kinetic energy.

Pushing on a car will not always change its mechanical energy. For the car's kinetic energy to increase, there must be a net force acting on the car in the direction of motion, allowing it to accelerate and gain speed. This change in kinetic energy is a result of the work done on the car by the applied force.

Burning paper converts the chemical energy stored in the paper into thermal energy (heat) and light energy. This energy comes from the chemical bonds within the paper breaking down and releasing energy in the form of heat and light as the paper combusts.

Depending on the medium, it could be "current" or "spark".

because of glucose

Elasticity.

The larger pot has more thermal energy because it has a greater mass of material that needs to be heated up. The thermal energy required to raise the temperature of a larger object is greater than that needed for a smaller object.

Energy can enter or exist an open system

Electricity provides the energy to light a light bulb. When the electricity flows through the filament in the bulb, it generates heat and light.

If an object is primarily using kinetic energy, it means that it is in motion. Kinetic energy is the energy an object possesses due to its motion. When an object is moving, it possesses kinetic energy which depends on its mass and speed.

A kettle has electrical energy when it is plugged in and heating up water. It also has thermal energy, as it heats up the water inside.

Kinetic energy is extra energy resultant of motion. So, a moving vehicle has kinetic energy.

A stop sign can have kinetic energy when it is being moved or transported, such as when it is being installed, transported in a vehicle, or hit by a moving object. The kinetic energy of the stop sign is due to its motion and is proportional to its mass and speed.

The energy in the prey it eats.

Wolves are carnivores, they eat meet. The animals they eat themselves eat grass and get their energy from the grass.

Grass is a plant and plants make their own food by trapping the energy in Sunlight.

Thus ultimately the Wolf's source of energy is the Sun.

The primary source of energy for trees is sunlight. Through the process of photosynthesis, trees convert sunlight into chemical energy in the form of sugars, which they use for growth and development.

Mechanical energy is the sum of an object's kinetic energy (energy of motion) and potential energy (energy of position). It is the energy associated with the motion or position of an object due to forces acting on it. This energy can be transferred between different forms but is always conserved in a closed system.

When you turn on an electric light, electrical energy is converted into light energy and heat energy. The electricity passing through the filament in the light bulb causes it to glow and emit light. Some of the electrical energy is also lost as heat due to resistance in the filament.

The potential energy stored in raised objects is gravitational potential energy. This form of energy is due to the object's position in a gravitational field and its ability to do work when it falls or moves to a lower position.
