It's a scalar. It makes no difference whether the 2 pounds is north or south,
up or down. In fact, just the thought is pretty silly.

What is the product of vector and scalar?
The scalar product of two perpendicular vectors is zero.In classical mechanics we define the scalar product between two vector a and b as:a · b = |a| |b| cos(alpha)where |a| is the modulus of vector a and alpha is the angle between vectors a and b.If two vectors are perpendicular, alpha equals 90º (or PI/2 rad) and cosine of alpha is, consequently, zero.So finally a · b = 0.
If a quart of strawberries weigh 2 pounds how many quarts of strawberries would weigh .25 ton?
If 1 quart of strawberries weighs 2 pounds, then 250 quarts of strawberries weigh 0.25 tons (ie, 500 pounds). It is a 1:2 ratio, and that is equal to 250:500.
What is meant by spin of the atomic particles as half and one?
Spin is the measure of the angle of the particle. The angle determines whether the particle is a scalar or a vector. Spin zero indicates a positive scalar; Spin 1/2 is pi/2 angle and indicates a positive vector; spin 1 is pi degrees and indicates a negative scalar; spin 3/2 indicates a negative vector.Physics Particles are Quaternions containing a scalar and vector parts, the unit quaternion is described as:cos(Angle) + v sin(Angle).Quantities in Physics are in general Quaternion, e.g. Gravitatioanl Energy W=-mu/r + cP.Bosons and Fermions represent pure scalars and Vectors with angle being multiples of pi or spin. spin is symbolic of 180 degrees spin zero is zero degrees. spin 1/2 is 90 degrees etc. When angles are not multiples of pi/2 the quantity is a Quaternion and contains a scalar (Boson) and Vector (Fermion).
How do you compare the units of work and kinetic energy?
Work and kinetic energy are defined as scalar energy and have the same units joules. dW=F.dr = (dP/dt) dr=dP(dr/dt) = dPv = vdP= mvdv W = F.r = mv^2/2. Physics has defined scalar energy but has no definition for vector energy mcV. Torque which is T= Fxr should be recognized as vector energy but it is defined as "Torque". This is another example of Physics not appreciating that the Universe is made of Quaternions, a Scalar part and a Vector part. E= FR = -F.R + FxR where the scalar energy has been defined as work (F.R) and the vector energy is defined as Torque FxR. Kinetic energy is a transformation of work in terms of mass and velocity versus force and distance. The vector energy is not called energy. See link: http://en.wikipedia.org/wiki/Torque
Advantages of vector quantization over scalar uantization?
Advantage of VQ over SQ: 1.For a given rate, VQ results in a lower distortion than SQ. 2.If the source output is correlate, vectors of source output values will tend to fall in clusters. 3.Even if no dependency: greater flexibility.
Is a scalar a component of a vector?
Answer: A vector is always the product of 2 scalars
Is it possible to multiply a vector quantity to a scalar quantity?
The product of scalar and vector quantity is scalar.
Diffrentiate between vector and scalar quantities?
Scalar quantities are defined as quantities that have only a mganitude. Vector quantities have magnitude and direction. Some example of this include Scalar Vector Mass Weight length Displacement Speed Velocity Energy Acceleration
Is the Cartesian coordinates a scalar or a vector or neither?
A vector is a magnitude with a direction, so if you have a line that is +2 on the x-axis and +2 on the y-axis, that would be a vector.
Is moment scalar or vector?
Is moment scalar or vector and why? Scalar has magnitude, but no direction. Vector has magitude and direction. Speed is a scalar. The car's speed is 25mi/hr. No direction is mentioned. Velocity is a vector. The car is traveling 25 mi/hr 20º North of East. Velocity is a vector, because it has magnitude and direction Moment has two meanings Moment of inertia = ∑ Mass* raidus^2 This moment measures how difficult it is to rotate an object. This moment is a scalar. Moment can also mean torque. Torque = Force x distance* sinθ (cross product). However torque can be clockwise or counter-clockwise. So torque is a vector.
Is Asmospheric pressure a scalar or vector?
The answer is simple, define both a scalar: 1 variable, and a vector: 2 variables. Pressure is a force of space over time, therefore Asmospheric pressure is a vector since it applies both space and time using 2 variables.
What is the product of vector and scalar?
The scalar product of two perpendicular vectors is zero.In classical mechanics we define the scalar product between two vector a and b as:a · b = |a| |b| cos(alpha)where |a| is the modulus of vector a and alpha is the angle between vectors a and b.If two vectors are perpendicular, alpha equals 90º (or PI/2 rad) and cosine of alpha is, consequently, zero.So finally a · b = 0.
Is potential energy a scalar or vector quantity?
Potential energy is a scalar quantity. Energy is the sum of a scalar part and a vector part. Energy W is the product of velocity V and momentum P; W = [c+V]P =[ -V.P + cP]. The Potential energy is the scalar energy -V.P=-vmv = -mv^2.Physicists consider energy a scalar quantity, but that is incorrect, energy is a Quaternion quantity, a scalar and a vector . The vector energy is the "Dark Energy" is hidden in plain sight, cP.
Why can't you add a vector quantity to a scalar quantity?
You can add a vector quantity to a scalar quantity. A complex number is just such an addition, z= a + bi. the first term 'a' is a scalar and the second term 'bi' is a vector quantity. The complex quantity z is the sum of a scalar and a vector. z is a different quantity than 'a' or 'bi', it contains both a scalar and a vector z=(a,bi). The Universe is made up of such additions called Quaternions: Q= a + bi + cj + kd , 'a' is a scalar and i, j and k are vectors making bi + cj +dk a three dimensional vector. Quaternions are four dimensional, one scalar dimension and three vector dimensions. Complex Numbers, z, a 2 dimensional number, are a subset of Quaternions.
Example of scalar and vector quantity?
Scalars:-- temperature; (68 degrees, no direction)-- cost; ($37.50, no direction)-- speed; (35 mph, no direction)Vectors:-- trip to the store; (2 blocks, West)-- force of gravity; (170 pounds, Down)-- velocity; (35 mph, North)
Is energy scalar or vector quantity?
A vector has magnitude and direction. A scalar has magnitude only. A car moving 60 mph North has a specific amouunt of kinetic energy, according to the formula KE = 1/2 * mass * velocity squared. If the car is moving 60 mph South is the KE the same?? ..Yes! Energy is a scalar! Nothing squared is a vector!! Length has direction. area does not
Is force a scalar or vector quantityhttp?
Both! Force is a quaternion quantity, the sum of a scalar force and a vector force. For example there are two gravitational forces, the scalar force Fs= - GmM d/dr 1/r = GmM/r^2 and the vector force Fv= Del -GmM/r = GmM R/r^3.
