# Physics Projects for Class 12

Physics is known as the science of energy and matter. It includes the study of energy, matter related to light, heat motions and force. Well, the extension of modern physics has expanded to nuclear physics, plasma, particles and cryogenics.

We are providing the best physics projects for class 12, explore the laws of physics and its role in our daily life with these physics fair projects. With these physics projects, you will be able to understand the law of motion and force, build models and machines. You will experience the force of magnetism and the power of the sun by these physics experiments.

If you are searching for physics projects ideas for your school science fair, then you came to the right place. At Byju’s you will find many ideas for physics projects. The projects described below are interesting as they have influence in real life. As a result, you will be more interested in learning them and gain knowledge about how the physics around us works in our real life.

Explore the cool physics projects, so that next time when you participate in a science exhibition, your project be unique and attractive.

Here are some examples of Physics Projects:

Electric car

In the electric car experiment the transmission of the force from the motor to a wheel axle is carried through two gears and a rubber band that acts as a belt. You will explore many things including a simple propulsion method of physics, design concepts, a concept of converting stored chemical energy into mechanical energy and a simple electric circuit.
Simple Machines – Electric Motor

The experiment of simple machine is bit tricky as the principle behind the magnetic field and electric current is a bit technical. But making a simple electric motor is easy. This experiment requires just a coil of wire, a magnet and a battery for power source.
Hooke’s Law: Calculating Spring Constants

Hooke’s law describes that an elastic object like a spring stretches in a proportion to the force that acts on them. The Hooke’s law give the following equation: $\small F = -kx$.. Here the minus (-) sign describes the flow is in the opposite direction of the force compressing the spring. The harder you pull the spring, it pulls back with the same force. Here is the Hooke’s law experiment on calculating spring constants.
How to Create a Visual Doppler

A sound source that moves in relation to you, its sound pitch changes. This sound effect establish that the source of sound is moving towards or away from you and you can also estimate its speed. This effect is called as Doppler effect. In this physics experiment you will create a model that describe and explain doppler effect.
