Definition
The acceleration of a moving point is the rate of change of its velocity. Note that the acceleration of a moving object is a vector, as it has both magnitude and direction. The acceleration is uniform when equal changes of velocity take place in equal intervals of time, in the ..
Definition
The speed of a moving particle is the rate at which it describes its path. Mathematically, this may be expressed in the following way. If a moving particle covers a distance s in a given interval of time, say, t then, the quantity s/t, is the measure of the speed of the moving particle at the inst..
Definition
If a ray rotates about the starting initial position, in anticlockwise direction, comes back to its original position after 1 complete revolution then it has rotated through 360 o . 1 complete rotation is divided into 360 equal parts. Each part is 1 o . Each part (1 o ) is divided into 60..
Equal Sets
Two sets A and B are said to be equal if and only if they contain the same elements i.e. if every element of A is in B and every element of B is in A. We denote the equality by A = ..
Equality of Matrices
If two matrices have their corresponding elements equal, then they are called equal matrices. Two equal matrices are exactly the same. If the given matrix A is of the order m x n, then its transpose will be of the order n x ..
Equality of Vectors
equal vectors Two vectors are said to be equal if they have the same magnitude and direction. In the figure below, three equal vectors have been represented. The equality of vectors is expressed in the following way Since the three vectors have the same direction, Mor..
Equality of Matrices
Two matrices are said to be equal if they have the same order and their corresponding elements are equal. e.g., then a = 1, b = 2, c = 3, d = 4, e = 5 and f = 6...
Equality of Matrices
If two matrices have their corresponding elements equal, then they are called equal matrices. If then a = p, b = q, c = r and d = s. a = 7, b = 9, c = 3. (i) Two equal matrices are exactly the same. (ii) If rows are changed into columns and columns into rows, we get a ..
