scalar quantities

The work done in moving a unit mass from infinity to a point in a gravitational field is called the gravitational potential at that point. It is a negative, scalar quantity. The unit is JKg - 1..

Gravitational Potential - The work done in moving a unit mass from infinity to a point in a gravitational field is called the gravitational potential at that point. It is a negative, scalar quantity. The unit is JKg - 1..

is defined as the amount of matter contained in it. The SI unit of mass is kilogram (kg). Mass is a scalar quantity. The amount of matter contained in a body does not change with time or from place to place i.e., mass of a body remains the same throughout the universe. Howe..

Distance is a scalar quantity. SI unit of distance is metre. The position of the bus changed when it moved from the terminus A to terminus B. There is a displacement of 150 km from A to B. The displacement by the return trip is also 150 km . ..

Distance Displacement It is the actual length of the path covered by a moving object It is the shortest distance between the initial and final positions of the moving object It is a scalar quantity It is a vector quantity ..

Work is said to be done when a force acts on an object and the point of application of the force moves in the direction of force. Conditions to be satisfied for work to be done: Some force must act on the object The point of application of force must move in the direction of force The product of th..

Distance - During motion in a straight line, the point object occupies a definite position on the path at each instant. Therefore, to describe the motion, one should specify the length of the path covered by the point object and the instant of time. The length of path covered by the object is the d..

Mass Weight 1 . It is the amount of matter contained in an object 2 . The mass of a body is constant throughout the universe 3 . Mass can never be equal to zero 4 . Mass is a scalar quantity 5 . SI unit of mass is kg 1 . It is the force with which an object ..

Let A = [a ij ] be a square matrix. We can associate with the square matrix A, a determinant which is formed by exactly the same array of elements of the matrix A. A determinant formed by the same array of elements of the square matrix A is called the determinant of the square matrix A and is denot..
