Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.
Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the ...
A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
Aside from the new series on the main channel, Crash Course Kids was launched in February on a new Crash Course Kids channel. [21] The series was hosted by Sabrina Cruz, known on YouTube as NerdyAndQuirky. [22] On October 12, 2016, the Crash Course YouTube channel uploaded a preview for Crash Course Human Geography.
Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology, etc.) deal with systems that seem to obey the laws of physics. According to physics, the physical laws of matter, energy, and the fundamental forces of nature govern the interactions between particles and physical entities (such as planets ...
MinutePhysics has collaborated with Vsauce, [11] as well as the director of the Perimeter Institute for Theoretical Physics, Neil Turok, and Destin Sandlin (Smarter Every Day). [12] MinutePhysics also has made two videos that were narrated by Neil deGrasse Tyson [ 13 ] [ 14 ] and one video narrated by Tom Scott . [ 15 ]

In physics, motion is when an object changes its position with respect to a reference point in a given time. Motion is mathematically described in terms of displacement , distance , velocity , acceleration , speed , and frame of reference to an observer, measuring the change in position of the body relative to that frame with a change in time.
