dimensional one

Let us consider a situation where the force is acting along the X-axis and the magnitude of the force is varying with position 'x'. Thus, as the ball moves, the magnitude of the work done by the force, on the ball, changes. The adjacent graph shows the plot of a one dimensional..

It is that elastic collision in which the colliding bodies move along the same straight line before and after the collision. Consider two bodies A and B of masses m 1 and m 2 respectively, moving along the same straight line, in the same direction. Let be their respective velocities, such..

Dimensional formula - It is the term which tells about the power with which a fundamental quantity is contained in a physical quantity. E.g., Dimensional formula of velocity is [LT - 1 ], that of density is [ML - ..

When velocity is defined using the fundamental units of mass, length and time, we have when there is no mass, M 0 = 1 (algebraic theory of indices). This is the dimensional formula for velocity and we can draw the following inference. Unit of velocity depends on the unit of..

Select the correct statement/statements. 1. A line is a set of points that extends in two opposite directions without end. 2. Lines of different sizes have different thickness. 3. A line is of finite length 4. A line is a straight one-dimensional figure having no thickness. => 2..

Dimensional equations are used to validate the correctness of a physical equation. Dimensional equations are used to derive correct relationship between different physical quantities. Dimensional equations are used to convert one system of units to an..

Dimensional analysis has no information on dimensionless constants. If a quantity is dependent on trigonometric or exponential functions, this method cannot be used. In some cases, it is difficult to guess the factors while deriving the relation connecting two or more physical qua..

Which figure represents the top view of the three dimensional figure? => Figure 2 or Figure 1 or Figure 4 or Figure 3..

Example, To check the correctness of v = u + at, using dimensions Dimensional formula of final velocity v = [LT - 1 ] Dimensional formula of initial velocity u = [LT - 1 ] Dimensional formula of acceleration x time, at = [LT - 2 x T] = [LT - 1h..
