We usually define vectors in terms of its magnitude and their orientation. Endgroup Ana S.

### This image shows a coordinate transformation from a global ECEF system to a local ENU system using ecef2enu.

**The magnitude of a vector can be different in different coordinate systems.**. Some physical quantities like distance either have no direction or none is specified. The magnitude of a vector can be different in different coordinate systems. So it does not matter what your choice of a coordinate system is it will not effect its direction and magnitude.

C i false ii true. Although its components may change if you change the coordinate system the vector is still the same. The scalar x-component of a vector can be expressed as the product of its magnitude with the cosine of its direction angle and the scalar y-component can be expressed as the product of its magnitude with the sine of its direction angle.

This direction angle is measured counterclockwise. A eq2D eq vector can have a component equal to zero even when its magnitude is nonzero f. Ii The magnitude of a vector can be different in different coordinate systems.

A_1 otimes a_2 b_1 otimes b_2 a_1 b_1otimes a_2 b_2 endgroup. The components of. The components of a vector can be different in different coordinate systems.

When we know the scalar components A x and A y of a vector vecA we can find its magnitude A and its direction angle theta_A. The direction of a vector can be different in different coordinate systems. The magnitude of Lorentz vectors are independent of those rotations and of boosts.

D i false ii false. No The magnitude of a vector can be different in different coordinate systems. B i true ii false.

A 2D vector can have a magnitude equal to zero even when one of its components it nonzero. The direction of a vector can be different in different coordinate systems. This direction angle is measured counterclockwise.

The components of the vector are different but in each system the magnitude of the vector is 224 units. The answer is True. It is possible to add a scalar to a vector.

A i true ii true. It is possible to add a scalar to a vector. If V3V1V2 then V3V1V2.

Often a coordinate system is helpful because it can be easier to manipulate the coordinates of a vector rather than manipulating its magnitude and direction directly. The magnitude of Cartesian vectors are invariant on rotations of the coordinate system. An arrow used to represent a vector has a length proportional to the vectors magnitude eg the larger the magnitude the longer the length of the vector and points in the same direction as the vector.

Now there are numeric facts about quantities that are independent of certain transformation of coordinate systems. I dont really understand how though seeing as magnitude and direction cannot be different and they are determined by the components but oh well. Magnitude and direction does not vary with the change of a coordinate system as they are independent of coordinates and will remain the same.

The position vectors start at the origin of each system and end at point P. An arrow used to represent a vector has a length proportional to the vectors magnitude eg the larger the magnitude the longer the length of the vector and points in the same direction as the vector. The direction angleor direction for shortis the angle the vector forms with the positive direction on the x-axisThe angle theta_A is measured in the counterclockwise direction from the x-axis to the vector Figure PageIndex3.

In a plane there are two equivalent coordinate systems. In a plane there are two equivalent coordinate systems. 100 13 ratings.

A 2D vector can have a magnitude equal to zero even when one of its components it nonzero. The magnitude of a vector can be different in different coordinate systems. The scalar x-component of a vector can be expressed as the product of its magnitude with the cosine of its direction angle and the scalar y-component can be expressed as the product of its magnitude with the sine of its direction angle.

The direction of a vector can be different in different coordinate systems e. Problem 3 3 points Vector -100 m -200 m and vector -300 m 400 m. The components of a vector can be different in different coordinate systems.

Vectors themselves may depend upon coordinate system the difference between two vectors also called the displacementif the two vectors are for example the postion vectors of some particle evaluated at two different times does not. The direction of a vector can be different in different coordinate systems. The magnitude of a vector can be different in different coordinate systems.

Translation of the. Jun 4 13 at 1712 begingroup Your operation could be also seen as a multiplication between tensorial products of two vectors that is. When we express a vector in a coordinate system we identify a vector with a list of numbers called coordinates or components that specify the geometry of the vector in terms of.

Some physical quantities like distance either have no direction or none is specified.
