Momentum is a vector quantity: it has both magnitude and direction.Since momentum has a direction, it can be used to predict the resulting direction and speed of motion of objects after they collide.
In engineering, physics, and chemistry, the study of transport phenomena concerns the exchange of mass, energy, charge, momentum and angular momentum between observed and studied systems. While it draws from fields as diverse as continuum mechanics and thermodynamics, it places a heavy emphasis on the commonalities between the topics covered ...
Tatiana L. Erukhimova (Татьяна Ерухимова) is a Russian-born American physicist. As a professor and The Marshall L’ 69 and Ralph F. Shilling ’68 Endowed Chair in the Department of Physics & Astronomy [1] at Texas A&M University, Erukhimova was elected a Fellow of the American Physical Society "for developing and disseminating innovative physics education programs for college ...
The moment of force, or torque, is a first moment: =, or, more generally, .; Similarly, angular momentum is the 1st moment of momentum: =.Momentum itself is not a moment.; The electric dipole moment is also a 1st moment: = for two opposite point charges or () for a distributed charge with charge density ().
She started making science videos while working as a mobile app developer at General Electric. [11] She started her channel Physics Girl on October 21, 2011. [12] In an interview with Grant Sanderson, she said that some of the earlier videos were later deleted from the channel. [9] Cowern has also participated in various events as a speaker.
MinutePhysics is an educational YouTube channel created by Henry Reich in 2011. The channel's videos use whiteboard animation to explain physics-related topics. Early videos on the channel were approximately one minute long. [2] As of March 2024, the channel has over 5.7 million subscribers.

In physics, action is a scalar quantity that describes how the balance of kinetic versus potential energy of a physical system changes with trajectory. Action is significant because it is an input to the principle of stationary action, an approach to classical mechanics that is simpler for multiple objects. [1]
