Physics Project for Class 12

Physics Project for Class 12

Physics is a fascinating subject that studies the laws of nature and the elements of the universe that includes light, matter, energy, force etc. An important branch of science, the subject works on the principle of observation and experimentation. Right from the very beginning, the concepts of Physics are taught but it is only in Senior Secondary Education that a separate book is dedicated to Physics and is taught as a separate subject. CBSE Class 12 Physics chapters cover a broad range of concepts that reinforce a student’s understanding of the subject. But being a practical oriented subject, it demands practical work and project work at the end of the course. If you are looking for Physics Project for Class 12, then below are some of the projects that you can consider.

Since you do not require to make hi-tech projects during in 12th class, simple and easy projects would be less time consuming and easier to explain. Electric car and electric motor are two of the most common projects. Given below are the details about the two:

Electric Car

Making an electric car for your Physics project for class 12th will set you apart from your classmates. It is easy to make and fascinating to see it work which makes it a perfect option for a project. The electric car works on a simple principle where the transmission of force from the motor to a wheel is carried through two gears and the use of rubber bands is made which acts as a belt. You will get to explore various concepts of physics like Aerodynamics, Conversion of Energy, Electric Circuit besides design while working on the project. 

Materials Required: A Plastic Board for Car Chassis; 4 Wheels; 4 Tire Rings; Battery Holder; Battery; Motor Mount; Electric Motor; Rubber Bands; Transmission Pulley; Screws; Paper Clips; Straw.

You can also make a Physics class 12 project on Convex Mirror and Lens!

Electric Motor

Electric Motor is one of the most common and basic projects that you can think of. Though the concepts involved in the motor are complex but making an electric motor is relatively easy. With just a requirement of a coil of wire, a magnet and a power source, it is a preferred choice for your Physics Project for Class 12 if you have limited time. 

Materials Required: Insulated Wire; Battery; Small Circular Magnet; Electric Tape; Modelling Clay; 2 Metal Sewing Needles; Knife.

How to Create a Visual Doppler

Aim: The following experiment is conducted to check what happens to sound waves by creating a visual model about what happens when a vehicle passes by. 

Theory: The explanation for the Doppler effect is that each successive wave crest is produced from a position closer to the observer than the crest of the previous wave, as the source of the waves is heading towards the observer. A visual simulation of what happens to the sound waves is created by this project to make them sound very different as the vehicle approaches than that when it exits.

Requirements: Ruler, Scissors, Tape, Toy car, Two pieces of colored construction paper, Some plain paper and a marker or a camera. 

Buoyancy 101

Aim: The following experiment is to check and determine whether a rise in water density would cause a boat hull to sink deeper in the water to an observable degree as its temperature is elevated from 5 degrees C to 95 degrees C.

Theory: This showed that increasing water temperature allows water molecules to move further out, decreasing upthrust in turn, and causing more water to be displaced by a floating mass as its buoyancy is decreased. If the water molecules spread outward due to high temperature, a large rise in water temperature can produce a noticeable difference in the water’s surface or even a small floating point.

Requirements: 10 Identical Styrene Model Boats, 128 grams of steel and a Digital Thermometer

Heat Transfer in an Incandescent Lamp

Aim: How much of the electrical power supply of an incandescent lamp is lost by thermionic emission from the filament? If these damages are large, the operational performance of incandescent lamps could be substantially increased by their elimination.

Theory: The power output can be decomposed into thermionic emission and thermal-radiation elements using the electricity, filament-temperature, and ambient-temperature details. The conduction is sequentially dependent upon temperature of the filament (Fourier’s Law), but the exposure is proportional to the fourth power of the temperature of the filament (Stefan-Boltzmann Law).

Requirements: 25-watt evacuated light bulb, programmable power supply, two high-precision digital meters, and a precise digital thermometer.

Insulation Value

Aim: The experiment is to equate straw insulation with traditional forms of insulation, which are fibreglass and rigid foam panels, which are widely used today.

Theory: The most critical element in building an energy effective contribution is adequate insulation. Insulation will hold the heat inside during cold days. Isolation will trap the sun outdoors on hot days. Insulation materials are structures that avoid the transmission of heat from a house inside and outside. To insulate walls, floors and pipes, various materials may be used.

Requirements: Speakers, Insulation and Digital Thermometer

Observations of Gas in the Infrared Spectrum

Aim: The aim of this project was to research the effect of gas chemical properties on its ability to process and transmit infrared radiation by gas transmission of infrared light. The primary aim was to mask a plainly transmissive gas heating element.

Theory: The molecular structure of gas can specifically influence transmissivity in the infrared spectrum is confirmed by the evidence from both forms of test. The  can of air has high absorption zones, allowing areas of low transmittance that caused some obstructing in the infrared spectrum.

Requirements: PVC pipe, Spectroradiometer, 8-12 micron infrared camera with digital imagery, Blackbody and gases.

Marvellous Magnetics

Aim: The purpose of this experiment was to decide how diamagnetism could influence levitation using graphite, paper, plastic, aluminium foil, or no substance.

Theory: In relation to how many man-made objects today use magnetism or even diamagnetism, this study may even interact with the earth. The world’s fastest train, for instance, is in Japan and runs on magnetism.

Requirements: Levitation Pedestal, Graphite, Adjustment Screw, Paper, Aluminum foil, and Plastic in place of the Graphite. 

Long and Short Wavelength Colors

Aim: The aim of the project is that the houses were painted in both solid colours (red, blue, green, orange) and mixed colours (red/blue and green/orange), this project examined the interior and exterior temperatures of houses and their insulation rates.

Theory: Data revealed that the order of internal temperature readings from peak to lowest matched the wavelengths of colour from longest to shortest fairly closely. Combination colour houses fell between their stable counterparts in general. Exterior temperature data shows that, followed by red, red/blue, grey, blue, orange, and control, the green/orange house was the warmest. The highest insulation rate, followed by green, green/orange, red/blue, red, orange, and control, was obtained from the blue home.

Requirements: Oil paints, Control house was painted white and Digital and Infrared Thermometers.

Use and Impact of Recycled Materials for Thermal Insulation

Aim: Fiberglass, pine shavings, polystyrene, polyurethane, cellulose, perlite, polyethylene foil, or bubble wrap were the goal of this experiment is to find which recycling process would be an effective electricity insulator.

Theory: This could be an asset in the summer, but even time would be spent on heating the house in the winter. It also took a bit longer than the other materials to cool fibreglass and only averaged around 12 minutes to heat it. As it warmed easily and also trapped heat to save energy, fibreglass was by far the most powerful insulator.

Requirements: Particle Board, Digital thermometer, Light Bulb and Cardboard boxes. 

Hydro Power

Aim: This following project is conducted to learn about the first-hand force of water.

Theory: At the foot of dams, hydropower plants are designed to take advantage of higher water pressure at the edge of a dam. The excess water is funnelled into a tube called a penstock into the dam. The water is then concentrated on a turbine’s blades. The water pressure of the water transforms the engine, and a power generator turns the turbine.

Requirements: Half gallon paper milk carton, Gallon of Water, Awl or 10p nail, Masking Tape, Ruler, Magic Marker, Pair of Scissors and Pad of Paper and Pencil to make Notes

Salt Water vs Tap Water

Aim: This experiment would be about magnet and water. Since water is diamagnetic, I used the magnets to transfer water, which means it appears to move further from magnets and electromagnets. A cookie tray with the magnets equally spread along the inside circumference of it.

Theory: Someone who studies water is a hydrologist. The study of the dynamics of electrically conducting fluids is called magnetohydrodynamics (MHD for short). One of them is saltwater. You could levitate a frog if you had a powerful enough magnet. Diamagnetic and paramagnetic are also compounds. In addition, this may be the data that I require. To see whether the water is flowing or not, I would have to use rubber duckies or food colouring.

Requirements: Rubber, Magnets, Angel food pie tin, Food coloring, Timer and Tape.
