Projectile motion on an Inclined plane

Projectile motion along an inclined plane: Let us consider an inclined plane that makes an angle  with the horizontal, as shown in figure. A particle is projected at time t = 0 with an initial velocity u at an angle  with the horizontal and it strikes the inclined plane at point A. Let us consider […]

Lami’s theorem in vector:

Lami’s theorem is used to relate forces with angle between them when three coplanar forces are acting from a point in equilibrium. The ratio of one force to the sine of angle between other two forces is constant. Statement and prove: According to Lami’s theorem, for a triangle, the ratio of one side with the […]

Unit dimension measurement Part – 5

Significant figure: Significant figure are the number of digits upto which the accuracy is maintain. Rules of significant figure: (i) All non-zero digits are significant. For example, 1.235 has four significant figures. (ii) The zeros appearing between two non-zero digits are significant. For example, 4.025 has four significant figures. (iii) All the trailing zeros after […]

Unit dimension measurement Part – 4

Accuracy precision and error measurement: Error: There is a difference between the true value and measured value when a physical quantity is measured by an instrument as the measuring instrument is not ideal. This difference is known as error. Accuracy: Accuracy of the measurement of a physical quantity is the closeness of the measured value […]
