(55 miles per hour) is a scalar.
(55 miles per hour heading north) is a vector.
40 miles in 1 hour 2 miles in 2(1/40) of hour or in 1/20 of hour or in 60/20 = 3 minutes
80 miles per hour
8.9 miles an hour.
well 40 miles per hour means that a car goes 40 miles in one hour... so if a car is going 80 miles in one hour and you divide the 80 and one hour by 2.. then you get 40 miles in 30 minures.. and the car is going 80 miles per hour.
200 miles per hour
No, it's a scalar quantity. ;)
60 mph is a scalar.60 mph north is a vector.
It is a scalar quantity unless you define direction, then it becomes a vector quantity.
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).
Velocity is a vector quantity, meaning that it has both a magnitude and a direction. Mass, on the other hand, is a scalar quantity; it has a magnitude only. Velocity is measured in units of distance divided by time; for example, meters per second or miles per hour.
TRUE. However, if you said '60 miles per hour in a northerly direction' , then that is a vector quantity. because it has direction.
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.
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.
Yes, it is a vector quantity.
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).
Speed is a scalar and velocity is a vector. A scalar only has magnitude while a vector has magnitude and direction. : Example: If you are traveling north at 65 miles an hour your speed is 65 miles an hour, your velocity is 65 miles an hour north. It gets a little more complicated. Speed = distance (a scalar)/time Velocity = Displacement (vector)/time Example: If you run 5 miles in an hour left and then 5 miles in a hour right your speed is 10 miles/2 hours = 5 miles an hour. However, since you end up in the same exact location as where you started your displacement is zero making your velocity zero as well. Think of it this way; since velocity is a vector it requires a direction if i ended up exactly where I started I have no direction, thus velocity must be zero. One more example to clarify: If you ran 6 miles right and 4 miles left in 2 hours, your speed will be 5 miles an hour (10/2=5) your velocity would be 1 mile an hour to the right, since displacement is 2 miles to the right (6 to right - 4 to left = 2 to right) and the time is 2 hours displacement/time = velocity; 2 to the right/2 = 1 mile to the right per hour.
