Speed is the rate of which an object is moving altogether and is a scalar quantity and thus only requires a magnitude and is found by the use of the formula speed=distance/time SI unit = m.s-1 Velocity is the rate of which a object is moving in a given direction, so is vector quantity and both a magnitude and direction are required found by the formula velocity=displacement/time SI unit = m.s-2

∙ 15y agobecause it has a magnitude but no direction, whereas vector quantities have a magnitude and a direction.

∙ 15y agoSpeed = distance/ time Velocity = displacement / time distance is scalar and displacement is vector

∙ 14y agospeed 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

∙ 7y agoVelocity is a vector. Speed is defined as the scalar component of velocity, so it's not a vector.

Is velocity a scalar quantity or vector quantity?
Velocity is a vector.Its magnitude is called 'speed'.
Why is velocity a vector quantity and speed is a scalar quantity?
Because it is: * A property of physical objects * Something that can be measured (or calculated from other quantities) Hmm, it is certainly not a physical quantity that is unique to the object! Velocity is relative to some other object. Thus, the can he threw traveled at 12m/s relative to the tree but 220m/s relative to that car.
Is specific gravity a vector or scalar quantity?
Gravity is a force, and forces have magnitude and direction; hence, it is a vector.
What is the quantity as acalar or vector?
A vector quantity has both size (magnitude) and direction involved but a scalar quantity only has size involved and not direction.
Is Electric displacement density scalar quantity?
no, it's a vector dude
Why is speed classifies as a scalar quantity and velocity classified as a vector quantity?
Speed = distance/ time Velocity = displacement / time distance is scalar and displacement is vector
Is momentum a vector or scalar quantity?
Momentum is a vector quantity. We know that momentum is the product of mass and velocity, and velocity has direction. That makes velocity a vector quantity. And the product of a scalar quantity and a vector quantity is a vector quantity.
Which is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
Is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
Color is classified as a vector quantity or a scalar quantity?
vector quality
Is velocity a scalar quantity or vector quantity?
Velocity is a vector.Its magnitude is called 'speed'.
Is the muzzle velocity a scalar or vector quantity?
I think Scalar
Is speed a scalar quantity or vector quantity?
Speed is a scalar quantity because it has magnitude but not direction, velocity is a vector quantity because it has magnitude and direction.
Why is speed classified as a scalar quantity and velocity classifed as a vector quantity?
Vectors have speed AND direction. Speed is classified as a scalar quantity because it only has magnitude (numerical value and unit of measurement) such as 50 mi/h. Velocity is classified as a vector quantity because it has magnitude and direction, 50 mi/h north. By including direction, you are giving more information than a scalar quantity (requiring one unit).
Why is speed classified as a scalar quantity and velocity as a vector quantity?
By their definitions: speed is how fast you're going, and velocity is how fast you are going AND what direction you're going in.
The main difference between a scalar and a vector quantity is?
A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.A vector quantity includes a direction; a scalar does not.
Is instantaneous velocity a vector quantity?
YES!!! Because velocity is speed in a given direction(vector). e.g 30 mph is a scalar quantity, but '30 mph in a northerly direction' is a vector quantity, because it has direction.
