Why is speed classified as a scalar quantity and velocity classified as a vector quantity?
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
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
Is instantaneous velocity a vector or scalar quantity?
Instantaneous velocity is a vector quantity.
Is the muzzle velocity a scalar or vector quantity?
I think Scalar
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 vector speed or velocity?
"Speed" is a scalar; "velocity" is a vector.
Is a vector quantity is always the same as a scalar quantity?
No, a vector quantity and a scalar quantity are different. A vector has both magnitude and direction, while a scalar has only magnitude. Velocity and force are examples of vector quantities, while speed and temperature are examples of scalar quantities.
Speed is to scalar quantity whereas velocity is to?
... a vector quantity. Speed is a scalar, meaning only the magnitude (a number) is used. If the direction of a movement is of interest, you use the word "velocity", instead, to describe the vector. A vector has both a magnitude and a direction.
Which is a vector quantity speed or velocity?
Velocity is a vector quantity because it includes both the speed of an object and its direction of motion. Speed is a scalar quantity because it only represents the magnitude of motion without direction.
Is acceleration a vector or a scalar?
Acceleration is a vector quantity because it has magnitude (amount of change in velocity) and direction.
How does a vector quantity differ from a scalar quantity?
A scalar quantity defines only magnitude, while a vector quantity defines both a magnitude and direction.
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.
Is momentum a vector?
Momentum is a vector quantity because the definition of momentum is that it is an object's mass multiplied by velocity. Velocity is a vector quantity that has direction and the mass is scalar. When you multiply a vector by a scalar, it will result in a vector quantity.
What is scalar vector?
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
