What else can I help you with?
Does average velocity and average speed have the same number?
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
Is velocity a vector or a scalar?
no its a vector quantity,not a scalar quantity,bcz still it z a velocity bt NT a speed On a typical journey the average velocity is the straight-line distance between the start and finish, divided by the time taken, and it also has a direction. The average speed is the actual distance run, divided by the speed. The average speed might not be equal to the magnitude of the average velocity. For example on a round trip the average speed might be 40 mph, while the average velocity is zero.
How is velocity diffrent from speed?
Velocity is a vector, and so it has two components -- magnitude (speed) and direction. Speed is a scalar, and it is the magnitude of velocity, a vector.
Is velocity a vector?
True ,velocity is a vector quantity ,it is specified by a magnitude and direction.
Is overall velocity the same as average speed?
No, velocity is a vector quantity (i.e. magnitude & direction) while speed is a scalar quantity (i.e. magnitude only).
The magnitude of a vector represents its?
That depends on what the vector, itself, represents. For example, if the vector represents velocity, then the magnitude of the vector represents speed. If the vector represents displacement, then the magnitude of the vector represents distance.
Which is vector speed or velocity?
"Speed" is a scalar; "velocity" is a vector.
Is velocity a vetor or scalar?
Velocity is a vector quantity because it has both magnitude (speed) and direction. Scalars are quantities that only have magnitude and no direction, while vectors have both magnitude and direction.
Is the average speed equal to the magnitude of the average velocity justify your answer?
Yes usually and no rarely, velocity is defined as a vector, having both a direction and a magnitude (which is speed in the case of velocity). For instance 100 mph (speed) east (0o) (direction). In this form it is easy to see that the magnitude is 100 mph but mathematically to determine the magnitude of a vector you would divide the vector by its direction. 100 mph 0o / 0o = 100 mph Average speed and average velocity share the same relationship as instantaneous speed and instantaneous velocity so divide out the average direction from your average velocity to determine your average speed. If this is over a time period and you know the beginning and ending places in space your averages will simply be the difference from the starting to the ending places. So yes so long as you define speed to actually be the magnitude of the vector. However, if speed is taken without direction over time it may become something different. If an object travels along a vector with a negative magnitude its speed will not be negative but its vector magnitude will. Ex: A car travelling in reverse still has a positive speed but a compass will show it to be heading in the opposite direction of travel, a negative vector value...
Why do we say that velocity is a vector and speed is not a vector?
Velocity is a vector because it has both magnitude (speed) and direction. Speed, on the other hand, is a scalar quantity that only has magnitude. Vector quantities require both magnitude and direction to be fully described.
What is velocity and why is it a vector?
Velocity is an indication of a speed, including a direction. It is a vector because that is how a vector is defined (a magnitude, including a direction).
Why is velocity a vector quantity?
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
