No it is not a vector
No. It is a speed (a scalar) but not a velocity (a vector).
A scalar times a vector is a vector.
Scalar
A scalar multiplied by a vector involves multiplying each component of the vector by the scalar value. This operation scales the vector's magnitude while retaining its direction if the scalar is positive, or reversing its direction if the scalar is negative. The result is a new vector that has the same direction as the original (or the opposite direction if the scalar is negative) but a different magnitude.
Time is scalar
(55 miles per hour) is a scalar. (55 miles per hour heading north) is a vector.
45 mph is a scalar quantity because it only has magnitude (45) but not direction.
No. It is a speed (a scalar) but not a velocity (a vector).
No, mph (miles per hour) is a scalar quantity, not a vector quantity. Scalar quantities have magnitude only, while vector quantities have both magnitude and direction. In the case of mph, only the speed or magnitude is specified, not the direction.
A scalar times a vector is a vector.
vector
A vector has magnitude and direction. A scalar has magnitude only. A car moving 60 mph North has a specific amouunt of kinetic energy, according to the formula KE = 1/2 * mass * velocity squared. If the car is moving 60 mph South is the KE the same?? ..Yes! Energy is a scalar! Nothing squared is a vector!! Length has direction. area does not
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
Vector quantities have direction as well as magnitude Vector: -displacement (10 m North) -velocity (100 mph south) Scalar -distance (10 m) -speed (100 mph)
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.
Traveling 60 miles per hour is a scalar quantity. Scalars only have magnitude and no direction, whereas vectors have both magnitude and direction. In this case, the speed of 60 miles per hour is the magnitude of the quantity without specifying a direction.
