it's a vector quantity because it is aquantity which only shows the speed of the vehicle but scaler shows direction also.
No. It is a speed (a scalar) but not a velocity (a vector).
Miles per hour and seconds are units of measurement of speed and time respectively, which are scalar quantities.
It is a scalar quantity unless you define direction, then it becomes a vector quantity.
scalar
Unfortunately this question can't be answered. The reason for this, is because there is no stated direction for the 'velocity' therefore it isn't a vector quantity, it's scalar.
(55 miles per hour) is a scalar. (55 miles per hour heading north) is a vector.
No. It is a speed (a scalar) but not a velocity (a vector).
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.
A scalar is a magnitude only (...I am driving at 60 miles per hour), while a vector is a magnitude and direction (...I am driving at 60 miles per hour, heading east).
Miles per hour and seconds are units of measurement of speed and time respectively, which are scalar quantities.
It is a scalar quantity unless you define direction, then it becomes a vector quantity.
No, thirty meters per hour is a scalar quantity because it only has magnitude (30 meters) and does not have direction. A vector quantity would include both magnitude and direction, such as 30 meters per hour due east.
TRUE. However, if you said '60 miles per hour in a northerly direction' , then that is a vector quantity. because it has direction.
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.
scalar
There is no such thing as 'scalar velocity'. Velocity is a vector, always. A quantity that tells how fast an object is moving but doesn't tell in which direction it's moving is a scalar. That quantity is called "speed". Three examples are: -- Driving 30 miles per hour. -- Running 8 miles per hour. -- Sliding 15 feet per second.
Vectors have the magnitude and direction, scalars have only magnitude. Addition of vectors A and B will produce a vector C. Such that C=A+B. C is a vector because it will have magnitude and the direction.For an example consider a moving sidewalk such as those in the airports. If such a sidewalk is moving South at 2 miles per hour, its velocity is vector A. If a person walking on that sidewalk at 3 miles per hour also South, that persons velocity is vector B. However, that person will be moving at 2+3=5 miles per hour in relation to a stationary observer or in other words with the velocity of vector C.Further, consider A+B1=C1.If that person is walking North, or the opposite direction of treadmill's (if he or she got on the wrong sidewalk :) ), that person's velocity will be -3 miles per hour that will be vector B1. Thus in relation to a stationary observer that person is moving 2+(-3)=(-1) miles per hour towards South, the velocity of vector C1. That is the person is moving North at 1 mile per hour.
