What are tensor quantities?
A tensor quantity is a physical quantity that is neither vector or scalar. Each point space in a tensor field has its own tensor. A stress on a material, such as a bridge building beam, is an example. The quantity of stress is a tensor quantity.
What are tensor quantities examples?
A physical quantity which is neither vector nor scalar is known as tensor quantity. A tensor field has a tensor corresponding to each point space. An example is the stress on a material, such as a construction beam in a bridge. stress is a tensor quantity.
What are tensors in physics?
A tensor is a concept from mathematical physics that can be thought of as a generalization of a vector. While tensors can be defined in a purely mathematical sense, they are most useful in connection with vectors in physics. In this article, all vector spaces are real and finite-dimensional.
What is tensor in simple words?
A tensor is a mathematical object. Tensors provide a mathematical framework for solving physics problems in areas such as elasticity, fluid mechanics and general relativity. The word tensor comes from the Latin word tendere meaning “to stretch”. A tensor of order zero (zeroth-order tensor) is a scalar (simple number).
Is electric current a vector?
Note: Current is a vector because it has a magnitude and a direction. Since current doesn’t obey it and it follows algebraic addition, currents are scalar.
What is tensor and scalar?
Tensors are simply mathematical objects that can be used to describe physical properties, just like scalars and vectors. In fact tensors are merely a generalisation of scalars and vectors; a scalar is a zero rank tensor, and a vector is a first rank tensor.
What is a tensor?
What is a tensor in engineering?
To put it succinctly, tensors are geometrical objects over vector spaces, whose coordinates obey certain laws of transformation under change of basis. Vectors are simple and well-known examples of tensors, but there is much more to tensor theory than vectors.
Is current a tensor quantity?
Both scalars and vectors are special cases of tensors. Current is a scalar. Current density is a vector. Because scalars and vectors are tensors this means current and current density are both tensors.
Is electric current a base quantity?
Electric current (I) was chosen by SI to be a base quantity – a fundamental physical quantity. A base quantity – though is not defined in terms of other quantities – can however be expressed in terms of other quantities.
Is electric current a scalar quantity or vector quantity?
Electric current is a scalar quantity. Any physical quantity is defined as a vector quantity when the quantity has both magnitude and direction but there are some other factors which show that electric current is a scalar quantity . When two currents meet at a point the resultant current will be an algebraic sum.
What do you mean by tensor?
In mathematics, a tensor is an algebraic object that describes a multilinear relationship between sets of algebraic objects related to a vector space. Tensors are defined independent of any basis, although they are often referred to by their components in a basis related to a particular coordinate system.
