Motion is everywhere from the motion of an elephant to the motion of the fastest aircraft. The study of motion is called Mechanics considering the motion of bodies that are large enough relative to the subatomic realm and the speed is considerably less than the speed of light.

The study of motion without considering the cause of motion is a part of Mechanics called Kinematics. The study of motion considering the cause of motion (force) is another part of Mechanics called Dynamics. Mechanics is the study of motion in relationship with the force and matter.

The waves which need medium to travel are called mechanical waves. In case of an earthquake, the disturbance travels in the form of seismic waves.

Wherever there occurs a disturbance and that disturbance moves or propagates, the moving disturbance is the wave and this carries energy. For example, the electromagnetic wave from the Sun warms us and seismic waves can destroy buildings.

The oscillating motion has a direct relationship with mechanical waves. The simple harmonic motion in mechanics has a direct relationship to the understanding of mechanical waves. The information of waves leads to the understanding of atomic structure.

Thermodynamics has the heart at the relationship between heat and mechanical work. The study of heat and its relationship with other forms energy and how this relationship relate to the properties of matter is called thermodynamics.

The thermodynamics laws we learn below will help you understand the heart of thermodynamics.

Electromagnetism is the combined study of electricity and magnetism. Electromagnetism is the study of electromagnetic interactions which includes electric and magnetic forces. Simply the electromagnetism is the study electromagnetic forces.

Most of the devices we use today such as computers, smartphones to electric motors, generators and many more devices and technology depend entirely on electromagnetism.
