Motion of a body vertically downward & vertically upward
Motion of a body vertically downward: When a body is releasedfrom rest at a certain height h, then equation of motion are reduced to v = gt h = ½gt² v² =…
Difference between speed and velocity
Speed: The rate at which a moving body describes its path is called as speed or the rate of change of distance with respect to time is termed as speed. E.g.; If the length of…
Angular Velocity
What is Angular Velocity? Give Definition and Formula? It is the rate of change of angular displacement of a body. It is usually expressed in revolutions per minute (r.p.m.) or radians per…
Angular Acceleration
What is Angular Acceleration, Centripetal Acceleration and Tangential Acceleration? Angular Acceleration is the rate of change of angular velocity. It is usually expressed in and is denoted by a Greek letter α (alpha). It…
Angular Displacement
Angular displacement is defined as “the angle in radians (degrees, revolutions) through which a point or line has been rotated in a specified sense about a specified axis”. It is…
Newton’s Laws of Motion
Motion:- When a body changes its position with respect to other bodies, then body is called as to be in motion. The entire subject of rigid body mechanics is based on three fundamental…
Center of Gravity
Center of Gravity (centroid) - The point through which the whole mass of the body acts, irrespective of the position of the body, is known as centre of gravity (briefly written as c.g.)…
Hexadecimal numbers
The complexity of computers requires higher order numbering systems such as octal (base 8) and hexadecimal (base 16) which are merely extensions of the binary system. A hexadecimal numbering system…
