The components of a vector will be the same no matter what coordinate system is used to express that vector?
Yes, that is correct. The components of a vector, which represent its magnitude and direction in a particular coordinate system, are independent of the choice of coordinate system used to express the vector. This property is a fundamental characteristic of vectors in mathematics and physics.
What is the relationship between the components of a vector and the unit vectors in a given coordinate system?
In a given coordinate system, the components of a vector represent its magnitude and direction along each axis. Unit vectors are vectors with a magnitude of 1 that point along each axis. The relationship between the components of a vector and the unit vectors is that the components of a vector can be expressed as a combination of the unit vectors multiplied by their respective magnitudes.
What are the Cartesian coordinates of the vector represented by the keyword "r vector"?
The Cartesian coordinates of the vector represented by the keyword "r vector" are the x, y, and z components of the vector in a three-dimensional coordinate system.
These give direction to a force vector?
The components of a force vector describe the magnitude and direction of the force in a specific coordinate system. The angle of the force vector is also important in determining its direction relative to the coordinate axes. Additionally, the sign conventions for the components indicate the orientation of the force along each axis.
What number is the length of a vector?
The length of a vector is a scalar quantity, typically denoted as a positive real number, that represents the magnitude or size of the vector. It is calculated using the vector's components in a coordinate system, often with the Pythagorean theorem.

What are the projections of a vector along the axes of a coordinate system?
A tangent of the vector is the projection of a vector along the axes of a coordinate system.

If you have selected a coordinate system you can express a two-dimensional vector using a pair of quantities known collectivelly as?
Components.

What is a projection of a vector along an axis of a coordinate system called?
The projection of a vector along an axis of a coordinate system is called a "component" of the vector. For a given vector, its component along a specific axis is determined by taking the dot product of the vector with a unit vector in the direction of that axis. This process effectively measures how much of the vector aligns with that axis. Each axis in the coordinate system has its own corresponding component of the vector.
How do you name the direction of a vector?
The direction of a vector is defined in terms of its components along a set of orthogonal vectors (the coordinate axes).
WHY DO POSITION IS A VECTOR QUANTITY?
To describe position, you need more than one number - for instance, an x-coordinate, a y-coordinate, and (if it is in three dimensions) a z-coordinate. That's the very essence of a vector - the fact that it is made up of several components.
Can the direction of a vector be different in coordinate systems?
Yes, the direction of a vector can be different in different coordinate systems if the basis vectors or axes of those coordinate systems are different. The numerical components of the vector may change, affecting how it is represented, but the vector itself remains unchanged.
What does gradient mean in math terms?
A vector having coordinate components that are the derived during the solving of a function.
