The (any) vector has 'direction' .
scalar has only a magnitude vector has both magnitude and direction
Vector quantity is a quantity characterized by magnitude and direction.Whereas,Scalar quantity is a quantity that does not depend on direction.
In programming languages, a string scalar is a sequence of characters. To define a string scalar, you enclose the characters in quotation marks. To manipulate a string scalar, you can perform operations like concatenation (joining strings together), slicing (extracting a portion of the string), and searching for specific characters or substrings within the string.
The product of a vector and a scalar is a new vector whose magnitude is the product of the magnitude of the original vector and the scalar, and whose direction remains the same as the original vector if the scalar is positive or in the opposite direction if the scalar is negative.
Speed is scalar quantity and velocity is a vector - velocity has both speed AND direction (You might say that velocity is speed with an attitude!)
It is a scalar quantity unless you define direction, then it becomes a vector quantity.
A scalar is just a number. A vector is a row or column of numbers. For example: 6 is a scalar while (1, 0, 23.5) is a vector.
there is no difference
No, readings on a digital voltmeter are scalar quantities. Voltage, which is what a voltmeter measures, is a scalar quantity representing the potential difference between two points in a circuit. It has magnitude but no specific direction, making it a scalar.
Yes, the scalar product of two vectors can be negative if the angle between them is obtuse (greater than 90 degrees). In this case, the result of the scalar product will be negative.
Yes, a scalar product can be negative if the angle between the two vectors is obtuse (greater than 90 degrees). The scalar product is the dot product of two vectors and is equal to the product of their magnitudes and the cosine of the angle between them. A negative scalar product indicates that the vectors are pointing in opposite directions.
In a given region of space, the scalar potential is related to the electric field by the gradient of the scalar potential. The electric field is the negative gradient of the scalar potential. This means that the electric field points in the direction of the steepest decrease in the scalar potential.
