What is energy and why does it matter to the rescue team? Power taken from other things. It is important because they need energy to power their devices. How can the rescue workers get energy to the batteries in their equipment during rescue missions?

Answer. Answer: Kinetic Energy is the energy of mass in motion. In a rescue mission, kinetic energy is the most used energy to carry out the rescue operation successfully. The machineries involved in the rescue mission like helicopters, submarines, lifeboats are all examples of kinetic energy.

They need convert the kinetic energy into potential energy and transfer it to a battery. The rescue workers can get energy to the batteries in their equipment during rescue missions by using a generator to convert the kinetic energy to potential energy. Potential energy is then stored in the battery.

Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over.

Human powered generators are the best energy source for the rescue team as it doesn’t require any lengthy time consuming resource but only the power of single human being. Just like fossil fuels, the human power is a kind of renewable energy source that does no harm to the environment and can be used whenever required.

In the final chapter of this unit, students converge on human-powered generators as the best source of energy for the rescue team.

Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.

Rescue workers even find it difficult to access energy for their electrical devices – because there is power outage. Some of these large-scale natural disasters are earthquakes, tornadoes, hurricanes, floods, etc.

Explanation:

• hurricanes.
• earthquakes.
• tornadoes.

When gasoline is burned in a school bus engine, the energy contained in gasoline is changed into heat energy. When we stand in the sun, light energy is changed into heat. When you turn on a flashlight, chemical energy stored in the battery is changed into light and heat. Energy is used to do work.

Various Forms of Potential Energy

• Elastic Potential Energy.
• Electrical (Electromagnetic) Potential Energy.
• Gravitational Potential Energy.
• Nuclear Potential Energy.

photovoltaic cell

Energy comes in six basic forms: chemical, electrical, radiant, mechanical, thermal and nuclear.

Solar cell, also called photovoltaic cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect.

Photovoltaic cells are based on a related phenomenon called the photovoltaic effect, and they convert light directly into electricity.

The theory, known as the Breit-Wheeler process, states that smashing together two particles of light, or photons, would create matter in the form of a negatively charged electron and its antiparticle, a positron. Both electrons and positrons have a small mass unlike photons, which have no mass.

Light is composed of photons, so we could ask if the photon has mass. The answer is then definitely “no”: the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits.

Light is a form of energy, not matter. Matter is made up of atoms. Light is actually electromagnetic radiation. Moving electric charge or moving electrons (electric current) cause a magnetic field, and a changing magnetic field creates an electric current or electric field.

Light do not occupy space, have no mass or volume, and therefore are not considered matter. Because matter is defined as anything which occupy space and have some mass.

Light energy is given off by things like stars, light bulbs, lasers, and hot objects. Our Sun – which is also a star – transmits light energy to Earth. The Sun is a natural source of light energy.

Light is a form of electromagnetic radiation with a wavelength which can be detected by the human eye. It is a small part of the electromagnetic spectrum and radiation given off by stars like the sun. Animals can also see light. The study of light, known as optics, is an important research area in modern physics.

Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun. The energy is released in the form of a photon and more photons come out as the substance gets hotter.

Light energy is an Electromagnetic radiation. It is referred to as visible light of electromagnetic spectrum. Light is a radiant energy and is an electromagnetic radiation which travels in a straight line and can be seen with the naked eye in the specific wavelength.

Light waves travel out from their source in straight lines called rays. Rays do not curve around corners, so when they hit an opaque object (one that does not allow light to pass through it), they are blocked from reaching the other side of that object.

It can travel through media like air and glass. It can also reflect from an object like a mirror. In the situations shown here, light interacts with objects large enough that it travels in straight lines, like a ray.
