What is he difference between speed and velocity?
http://wiki.answers.com/Q/The_difference_of_speed_and_velocity" The difference between speed and velocity is that speed is a scalar quantity(that have only magnitude) and velocity is a vector quantity(that have both magnitude and direction).
What is a scalar which is both positive and negative?
Scalar is a type of quantity which contains magnitude only and has no direction. For example: distance and speed
Examples of scalar quantities?
length,area,volume,speed,mass,density,pressure,temperature,energy,entropy work,power & charge.
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.
Is The slope on a position-time graph is representative of the acceleration of the object?
No. Slope of position/time graph is speed, or magnitude of velocity.Slope of speed/time graph is magnitude of acceleration.
How is speed difrent from velocity?
Velocity has magnitude and direction and speed only has magnitude.
Does constant speed depend on direction?
no,because speed is scalar which has magnitude only meanwhile velocity is vector which has magnitude and direction
Is speed a scalar quantity?
speed has only magnitude but no direction associate to it, if you consider velocity it consists of magnitude along with the direction. Hence speed is considered as a scalar quantity
Why can velocity be negative but nonzero speed is always positive?
speed is a scalar quantity with magnitude only but no direction; velocity is a vector with both magnitude (speed) AND direction, which could be positive or negative
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).
How is velocity and speed different?
Velocity has a direction.
Why is speed a scalar quantity but a velocity a vector quantity?
Speed is only a magnitude (single value) while velocity is both magnitude and direction. Direction is a vector.
Is velocity scalars or vectors?
It is a vector since it has both a magnitude and a direction. Scalar quantities only have a magnitude.
A velocity vector tells you two things?
Speed (which is a magnitude), and the direction.Speed (which is a magnitude), and the direction.Speed (which is a magnitude), and the direction.Speed (which is a magnitude), and the direction.
What is Scalar Velocity?
Velocity is a vector , which it means it has both magnitude and direction. Scalars have only magnitude. The magnitude of a velocity vector is usually called speed . Although I have never heard it called by that name, scalar velocity is speed.
Diference between velocity and speed?
Velocity has speed and direction. Speed only has speed. --------------------------------------------------------------------------------------- Speed is a scalar quantity having only magnitude But velocity is a vector quantity having both magnitude and direction. So a body is said to move with uniform speed around a circle but not with uniform velocity as the direction is always changing.
Can a change in velocity always indicate a change in speed?
Velocity has direction as well as magnitude. Speed only has magnitude. So the velocity of something can change without its speed changing. This is what is happening when something is going in a circle.
