# Is inertia scalar n vector quantity?

Inertia is due to mass. Mass is scalar. Hence inertia too is a scalar

### Difference between pressure and force?

Pressure is scalar but force is a vector. Pressure is defined as the force per unit area. As we multiply area vector by the pressure which is scalar, we get the force vector. This is similar to get momentum vector by multiplying velocity vector by the mass which is scalar. Unit of force is newton but unit for pressure is N m-2

### What is the importance of scalar and vector quantity?

Scalar quantity is the usual one. It is already there unavoidable. But vector is the new one. Why do we need it? Suppose say two persons by name John and Johann push a box with forces 4N and 3N, what could be the effective force on the box? One may say 7 N by adding them. One may say just 1N because of getting the difference. Another may say 5N. How? Why do they give…

### Is it true that force is a vector?

No! Force can be a scalar or a vector and both. It is true that force is a quaternion, the sum of a scalar and a vector! There are two kinds of numbers in physics real numbers also called scalars and vector numbers. Hamilton discovered this in 1843 when he invented Quaternions. Real numbers have positive squares and vector numbers have negative squares. Vectors are denoted by I, J and K unit vectors real numbers…

### What is the difference between zero and vector zero?

The zero vector occurs in any dimensional space and acts as the vector additive identity element. It in one dimensional space it can be <0>, and in two dimensional space it would be<0,0>, and in n- dimensional space it would be <0,0,0,0,0,....n of these> The number 0 is a scalar. It is the additive identity for scalars. The zero vector has length zero. Scalars don't really have length. ( they can represent length of course…

### Does torque and work are equivalent?

Though torque and work has the same unit N m, we cannot say that they are equivalent. Torque is moment of the force about a fixed point or line. But work is said to be done as the point of application of the force gets displaced. In case of torque we have to multiply force and perpendicular distance. But in case of work, we multiply force and the component of displacement in the direction of…

### What is scalar force and vector force in the force?

To put it simply, scalar is essentially just a number of the force, such as 10 newtons whereas a vector is a force with a direction such as 10 newtons south. Answer2: Forces like many quantities in Physics are Quaternions. Quaternions consist oa a scalar number and three vector numbers. Quaternions can be viewed as Angles and Axis. Positive Scalar forces have angles of 360 degrees and negative scalar forces have 180 degrees rotation. Positive…

### What is the equation for inertia?

Definition A simple definition of the moment of inertia (with respect to a given axis of rotation) of any object, be it a point mass or a 3D-structure, is given by: where m is mass and r is the perpendicular distance to the axis of rotation. Detailed analysis The (scalar) moment of inertia of a point mass rotating about a known axis is defined by The moment of inertia is additive. Thus, for a rigid…

### Are velocity and displacement a pair of vector quantities?

Yes they are. Vector quantities has both magnitude and direction, whereas scalar quantities only have magnitude. Examples of vector quantities: Displacement (Δd) - 10 m [W] or 36 km [W] Velocity (v) - 10 m/s [60° N of W] or 36 m/s [60° N of W] Acceleration - 9.8 m/s2 [↓] - this value is the acceleration dude to gravity (if we ignore air resistance).

### What does Newton's second law of motion states?

Newton's 2nd law states that vector force F is proportional to acceleration A; F = mA. This law is related to the vector energy cP, F= dcP/dr = cdP/cdt = dP/dt = mdV/dt = mA. Energy is a Quaternion quantity. Newton's scalar energy -mGM/r gives f=- d(mGM/r) /dr = mGM/r2 = vp/r = vp/ct = (v/c)mv/t = (v/c) ma = 1/n ma.

### What describes unequal forces acting on an object - results in change in the object's motion?

Newton's 2nd Law of Motion states that F = m * a, where F = the net force acting on an object [N]; m = the mass of the object [kg]; and a = acceleration [m/s2] . If the motion is linear, then we can consider scalar operations on F and a. If the force is a vector, then a has to be a vector too. ============================

### Is eigenvalue applicable only to n x n matrices?

The answer is yes, and here's why: Remember that for the eigenvalues (k) and eigenvectors (v) of a matrix (M) the following holds: M.v = k*v, where "." denotes matrix multiplication. This operation is only defined if the number of columns in the first matrix is equal to the number of rows in the second, and the resulting matrix/vector will have as many rows as the first matrix, and as many columns as the second…

### What is boson and fermion?

Bosons and Fermions are parts of Quaternion Electronic Particles. The Boson is the Quaternion Scalar part and the Fermion is the Quaternion Vector part. Quaternions are four dimensional "particles" a Boson and a three dimensional Fermion The Quaternion Unit can be described by Q= Cos(Spin) + v Sin(Spin) where v is the unit vector. The Quaternion consists of a scalar part the Boson = Cos(Spin) and a vector part the Fermion = v Sin(Spin). When…

### What realtionship does mass have with weight?

mass is a scalar quantity, while weight is a vector quantity. In particular, weight is defined as the force experienced by a some body of mass due to gravity. On earth, near the surface, the weight of any object is the product of its mass(Kg) and the acceleration experienced by gravity (m/s^2). In equation form. Weight (N) = mass (m) * 9.8 (m/s^2) for example a ball with mass of 10kg has a weight equal…

### Weight and mass are different describe how they are different?

Weight and mass are different. Here are some points of difference. Mass | Weight 1. It is the amount of matter contained in | It is the force with which a body is attracted the body | to the center of earth | 2. It is a scalar quantity | It is a force so a vector quantity. | 3. it is a constant quantity(from place to | It may vary from place to place…

### Are speed and distance a pair of vector quantities?

Speed and distance are examples of scalar quantities, meaning they only have magnitude. Velocity and displacement are vector quantities, meaning they have both magnitude and direction. Examples of scalar quantities: speed (s) - 10 m/s or 36 km/h distance (d) - 100 m or 0.1 km Examples of vector quantities: velocity (v) - 10 m/s [E] or 36 km/h [E] displacement (Δd) - 100 m [E] or 0.1 km [E] The value in square brackets…

### If you weighed 70 pounds on earth how many pounds would you weigh on a neutron star?

The gravitational field of the neutron star is about 2 x 10^11 times stronger than the gravitational field of earth. However, you have provided a mass in the question and this would remain the same if you were on a neutron star (mass is a scalar quantity - a common mistake). Weight is a vector quantity obtained by mulitplying mass in kg (70 pounds would be about 32kg) by the gravitational field experienced - so…

### Write a program in C language to find out the dot product of two vector quantities in Cartesian?

#include <stdio.h> #include <ctype.h> #define n[] int main() { int n, result , answer; int a[n], b[n]; printf("Enter number of terms you would like to use :"); scanf("%d", &n); printf("Enter first vector:\n"); scanf("%d", &a[n]); printf("Enter second vector:\n"); scanf("%d", &b[n]); printf("The dot product is \n" ); return 0; }

### What theory does the experiment of force between two parallel currents work?

Quaternion Vector Theory: The currents have vector direction I and -I; II= - Minus scalar sign indicates attraction; I(-I) = + Positive scalar sign indicates Repulsion. Thus parallel lines with current in the same direction bow-n; parallel lines with opposite currents bow-out. This result can be reasoned in the first case that the magnetic field created by the currents is reduced between the wires (opposite flow) and increased outside the wires and thus the wires…

### What do you exactly mean by magnitude?

The amount is known to be magnitude of a physical quantitiy. 2 second. 2 is the magnitude of time. 5kg, here 5 is the magnitude of the mass. 76 N, this is for the force whose direction is also to be mentioned. Apart from that it has magnitude of 76 N. Those having only magnitude are termed as scalar quantities and those having direction too are taken as vector quantities.

### C program to read and print a scalar matrix?

Here is the C program to check whether the inputted matrix is scalar matrix or not. ( its not my creation, its get from other website,am not check) #include<stdio.h> #include<conio.h> int main() { int a[10][10],i,j,m,n,f=0; printf("Enter the order of the matrix\n"); scanf("%d%d",&m,&n); printf("Enter the matrix\n"); for(i=0;i<m;i++) { for(j=0;j<n;j++) { scanf("%d",&a[i][j]); } } if(m!=n) { printf("The matrix is not identity"); } else { for(i=0;i<m;i++) { for(j=0;j<n;j++) { if((i==j&&a[i][j]!=a[0][0])(i!=j&&a[i][j]!=0)) { printf("The matrix is not scalar\n"); f=1; break…

### C plus plus program for hamiltonian cycle algo?

### When the size of vetor is fixed in c plus plus?

The size of a vector cannot be fixed because a vector is a wrapper for a dynamic array where resizing occurs automatically (by virtue of the vector class). So, even if you reserved enough memory for n elements in advance, the vector will resize automatically as soon as you push more than n elements. A normal dynamic array does not resize automatically (you have to manually resize the array in order to accommodate more elements…

### How would I add numbers input by a user one at a time into a vector in MATLAB I have the loop set up but don't know how to add the data into the vector?

First, make sure your vector is initialized outside of the loop. Then, within your loop you need to update the vector. If you want data entered by the user only, you should initialize with an empty vector. Example program (not sure which loop you're using, but I'll use a while loop here): vector=[]; user='y'; while user=='y' user=input('Enter another variable? Type y for yes and n for no: '); if user=='n' break end var=input('Please input variable…

### What is the column vector?

In mathematics a vector is just a one-dimensional series of numbers. If the vector is written horizontally then it is a row vector; if it's written vertically then it's a column vector. Whether a vector is a row or a column becomes significant usually only if it is to figure in multiplication involving a matrix. A matrix of m rows with n columns, M, can multiply a column vector, c, of m rows, on the…

### Calculate the acceleration of a 82 kg couch that is pushed across the floor with an unbalanced force of 21 N?

Newton's 2nd Law of Motion: F [N] =m [kg] *a [m/s2], where F = net force acting on an object; m = mass of the object; and a = acceleration of the object. Rearrange the equation: a = F / m = 21 [N] / 82 [kg] = 0.2561 [m/s2]. Note that scalar quantities for F and a are assumed. This statement is true when the motion is linear (a straight line). The situation will…

### What is the difference between the ''dot product'' and the ''cross product''?

Dot Product: Given two vectors, a and b, their dot product, represented as a ● b, is equal to their magnitudes multiplied by the cosine of the angle between them, θ, and is a scalar value. a ● b = ║a║║b║cos(θ) Cross Product: Given two vectors, a and b, their cross product, which is a vector, is represented as a X b and is equal to their magnitudes multiplied by the sine of the angle…
