what are the three base dimensions in classical mechanics?

In classical mechanics there are three base dimensions. Length is one of them. What are the other two? acceleration and mass acceleration and time acceleration and charge mass and time mass and charge time and charge Correct There are three dimensions used in mechanics: length ( ), mass ( ), and time ( ).

A two-dimensional (2D) object is an object that only has two dimensions, such as a length and a width, and no thickness or height. A three-dimensional (3D) object is an object with three dimensions: a length, a width, and a height.

Principle axis of moment of inertia is the axis passing through centroid or centre of gravity of body. ... A set of three orthogonal lines consisting of these two and a line perpendicular to both are the principal axes of inertia of the figure relative to that point.

Think of the x coordinate of the force as the base of a triangle, the y component as the height of the triangle, and the hypotenuse as the resultant force from both components. Extending the link, the angle the hypotenuse makes with the base is the direction of the force. So, 5 N is the magnitude of force.

Newton's theory assumes quantities like space,time ,length,mass etc to be absolute(called classical physics),while in the theory of relativity ,all of the above quantities are relative and changes for different observers(relativistic physics).

In everyday life, we inhabit a space of three dimensions – a vast 'cupboard' with height, width and depth, well known for centuries. Less obviously, we can consider time as an additional, fourth dimension, as Einstein famously revealed.

In physics, a frame of reference (or reference frame) consists of an abstract coordinate system and the set of physical reference points that uniquely fix (locate and orient) the coordinate system and standardize measurements within that frame.

Any location in space can be described with respect to the surface of the earth: Latitude, Longitude, and Height. 3 parameters, because space is 3 dimensions. There are only 3 directions, and any other direction is actually a sum of multiples of these three directions. That's why there are only 3 dimensions.

It is the 4th dimension, but in a different sense than simply going from 2D to 3D. The reason why time is regarded as the 4th dimension is that in relativity, we have to include the time coordinate in describing events fully in space along with the time, called the space-time coordinate.

A rectangular prism has three dimensions: length (l), width (w), and height (h). Another way to think about the volume formula is as follows: V = l w h = (l w) h. Since l w is the area of the prism's base, you can think of the volume formula as the area of the base times the height, or V = Bh.

In contrast, Spaceland (the three-dimensional world as humans understand it) contains height, length, and width, so an object can be rotated and examined from several angles. Flatland has only one angle because it has only one plane; Spaceland has three and so can be viewed on a larger scale.

To motivate the fundamentals of QFT, an overview of classical field theory is in order. The simplest classical field is a real scalar field — a real number at every point in space that changes in time. It is denoted as ϕ(x, t), where x is the position vector, and t is the time. Suppose the Lagrangian of the field is.

In mathematics, a set B of elements (vectors) in a vector space V is called a basis, if every element of V may be written in a unique way as a (finite) linear combination of elements of B. The coefficients of this linear combination are referred to as components or coordinates on B of the vector.

The world we live in is called the Three Dimensional World or more commonly known as the 3-D World. What is meant by this is that our world(the world we can see and observe) is made up 3 things: Length, Breadth and Height.
