vector
scalar
Specific charge is a scalar quantity. It is the ratio of a charge to its mass, and does not have a direction associated with it.
A scalar is a magnitude that doesn't specify a direction. A vector is a magnitude where the direction is important and is specified.
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.
Hours is a scalar quantity, as it only represents the magnitude of time elapsed and does not have a direction associated with it.
Charge is a scalar quantity because it only has magnitude and no direction.
A scalar times a vector is a vector.
vector
Electric potential is a scalar quantity since work done and charge are scalars
No, electrical charge is a vector quantity because it has both magnitude and direction.
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
Scalar
When multiplying a vector by a scalar, each component of the vector is multiplied by the scalar. This operation changes the magnitude of the vector but not its direction. Similarly, dividing a vector by a scalar involves dividing each component of the vector by the scalar.
An earthquake is neither a scalar nor a vector. It is an event.
vector
Yes, you can multiply a vector by a scalar. The scalar will multiply each component of the vector by the same value, resulting in a new vector with each component scaled by that value.
