Web25 Jan 2024 · Stress Definition in Physics. Stress is defined as the restoring force acting per unit area of a body. Thus, stress is a quantity that describes the magnitude of forces that cause deformation on a unit area. When forces pull on an object and cause elongation, like the stretching of an elastic band, we call it tensile stress. Webscalar, a physical quantity that is completely described by its magnitude. Examples of scalars are volume, density, speed, energy, mass, and time. Other quantities, such as force and velocity, have both magnitude and direction and are called vectors. Scalars are described by real numbers that are usually but not necessarily positive. The work done on … Web31 May 2024 · Explanation: In the case of electric current , although it has direction, but when the two current collides or meets their sum is equal to the algebric sum and not vector sum (i.e it does not follow the parallelogram of vector addition). Hence it is a scalar quantity and is not a vector even though it has direction. mufasa talking to simba in the clouds

Is time a scalar or vector? - TimesMojo

Web4 Nov 2024 · It is how fast an object is moving. Velocity is a vector quantity that indicates displacement, time, and direction. Unlike speed, velocity measures displacement, a vector quantity indicating the difference between an object's final and initial positions. Speed measures distance, a scalar quantity that measures the total length of an object's path. WebSo a tensor of type (p,q) is a multiplicative symbol from p copies of a single vector space V and q copies of its dual space V * . The set of all multiplicative symbols of this kind is called a tensor product space. So for short, a mathematician may just say "a tensor is an element of a tensor product [space]".

Web17 Sep 2024 · A vector can be used to represent quantities or values in an application. The size (also called dimension or length) of the vector is the number of elements it contains. The size of the vector determines how many quantities are in the vector. We often refer to the size of a vector using the variable n. So an n-vector has n values. Web14 Apr 2024 · A. No, a rank-1 tensor and a vector are the same things. A rank-1 tensor is defined as a tensor with one component, which is equivalent to a vector. Conclusion: In summary, vectors and tensors are mathematical objects that play an essential role in describing and understanding many physical and mathematical systems.
