Hello Friends!! I am lokesh from quickstudyhelper.com. In this blog, we will discuss the Top 20 Topics For Physics Presentation. There are many topics for presentation but we will discuss which topic is very popular and important. and here we will give the topic and quick definition.
Best 20 Topics For Physics Presentation
Top 20 Topics For Physics Presentation: Physics is a huge branch of nature science. Physics is difficult to define. According to the opinion of some scholars, it is a science of energy and it discusses the conversion of energy and its material relations. Through this, the study of the Prakrit world and its internal actions are studied.
Physics Topics For Presentation:
It is a major department of science. Its principles are valid throughout science and apply in every part of science. Its area is wide and setting its limits is very difficult. All scientific subjects come under this in a small amount. Other branches of science are either directly based on the physical, or try to relate their facts to its basic principles.
List of 20 Topics For Physics Presentation
1.FUTURE SOURCE OF ENERGY
Atomic energy, solar energy, and energy from wind and biofuels are just a few of the promising alternatives for a cleaner and greener future. Other relatively new sources of energy such as fuel cells, geothermal energy, and ocean energy are also being explored.
2.DARK MATTER AND DARK ENERGY
Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. A hypothetical form of energy that produces a force that opposes gravity and is thought to be the cause of the accelerating expansion of the universe.
3.HYDRO ELECTRICITY
Hydroelectric power, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy.
4.FIBRE OPTICS COMMUNICATION
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information.
5.SATELLITE
A satellite is a moon, planet, or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. … Usually, the word “satellite” refers to a machine that is launched into space and moves around Earth or another body in space. Earth and the moon are examples of natural satellites.
6.WIRELESS ELECTRICITY
Wireless power transfer, wireless power transmission, wireless energy transmission, or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link.
7.LASER
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term “laser” originated as an acronym for “light amplification by stimulated emission of radiation”.
8.SENSORS
A sensor is a device, module, machine, or subsystem whose purpose is to detect events or changes in its environment and send the information to other electronics, frequently a computer processor. A sensor is always used with other electronics.
9.THE BIG BANG THEORY
The Big Bang Theory is a cosmological model of the observable universe from the earliest known periods through its subsequent large-scale evolution.
10.PLANETARY MOTION AND GRAVITY
Newton’s laws of motion and gravity explained Earth’s annual journey around the Sun. Earth would move straight forward through the universe, but the Sun exerts a constant pull on our planet. This force bends Earth’s path toward the Sun, pulling the planet into an elliptical.
11.KEPLER’S LAW
Three theorems describing orbital motion. The first law states that planets move in elliptical orbits with the sun at one focus. The second states that the radius vector of a planet sweeps out equal areas in equal times. The third law relates the distances of the planets from the sun to their orbital periods.
12.ARTIFICIAL INTELLIGENCE
In computer science, artificial intelligence, sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and animals.
13.DOPPLER EFFECT IN SOUND AND LIGHT
When wave energy like sound or radio waves travels from two objects, the wavelength can seem to be changed if one or both of them are moving. This is called the Doppler effect.
14.QUANTUM MECHANICS
The branch of mechanics that deals with the mathematical description of the motion and interaction of subatomic particles, incorporating the concepts of quantization of energy, wave-particle duality, the uncertainty principle, and the correspondence principle.
15.EINSTEIN’S THEORY OF RELATIVITY
General relativity, also known as the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics.
16.PHOTOELECTRIC EFFECT
The photoelectric effect is the emission of electrons or other free carriers when electromagnetic radiation, like light, hits a material. Electrons emitted in this manner can be called photoelectrons.
17.STRING THEORY
String theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. It describes how these strings propagate through space and interact with each other.
18.TOUCH SCREEN
The touch screen is an electronic visual display that a user can control by touching their fingers on top of the screen, that is, they can do their work. A touchscreen gives the user a chance to interact more directly with the system than with a mouse.
19.GEOTHERMAL ENERGY
Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth’s crust originates from the original formation of the planet and from the radioactive decay of materials.
20. THE PHYSICS OF FIRE
Fire is the rapid oxidation of combustible materials, causing heat, light and many other chemical repellent products such as carbon dioxide and water. Are generated. Oxidized gas ionized plasma. Due to the inherent inaccuracy in combustible material, the color of flame and the intensity of fire can be different. Fire in general produces dah which has the ability to physically damage substances.
