Three types of mechanical waves are transverse waves, longitudinal waves and surface waves. Mechanical waves are different from electromagnetic waves in that they can't propagate in a vacuum; they need a physical medium, such as water or air.


Sound waves, earthquakes and ocean waves are all examples of mechanical waves. Longitudinal waves, transverse waves and surface waves are the three types of mechanical waves.


Electromagnetic and mechanical waves differ in that electromagnetic waves are always longitudinal and do not require a known medium, while mechanical waves are either longitudinal or compression waves and require a medium. All known electromagnetic waves are also known as forms of light. An example


Sound is classified as a mechanical wave because it requires a medium to propagate its energy and cannot be heard in vacuum.


A mechanic is most often a trained service professional who inspects, maintains and repairs cars and light trucks. A licensed mechanic may specialize in a number of other fields.


A mechanical force involves contact with another object. Mechanical forces are distinguished from the four natural forces of electromagnetism, the strong nuclear force, the weak nuclear force and gravity. While each of the four natural forces do not require a physical connection, mechanical forces m


Mechanical engineering is the branch of engineering that deals with design, construction and use of machines. Mechanical engineering can be used to build small individual parts or giant systems.


Mechanical energy is the sum of all the forces acting on or in a system as a result of its chemical state (chemical-potential), relative position (potential) and state of motion (kinetic). Work, or a force acting upon an object, is the use of mechanical energy to affect a system.


Mechanical weathering is the erosion of rock caused by physical processes. Extreme temperature changes and constant exposure to water or air are common causes of mechanical weathering.


A mechanical mixture is one that can be separated through mechanical means, such as a magnet or a centrifuge. Mechanical mixtures are not chemically bonded.
