What affects gravitational acceleration

g depends upon 1) height of the body 2) Depth of the body below earth surface 3) Lattitude 4). Due to rotation of earth Click to see complete derivation simplified notes

What is Coulomb's Law and Principle of Superposition

Thank you for making learning fun The force of interaction (attraction or repulsion) between two point charges is directly proportional to the product of their masses and inversely proportional to the square of their distance. K is the proportionality constant. It depends upon nature of medium separating the charges and on the system of units.

Relation between universal gravitation constant (G) and gravitation acceleration (g)

Relation between universal constant (G) and gravitational acceleration (g) m = mass of falling object Then, gravitational acceleration force, By the second law of newton's velocity law, Now on comparison of eq n (1) and (2), we say that eq n (1) =eq n (2) We know that the formula of density is,

Newton's law of gravitation

Index: Newton's law of gravitation Acceleration due to gravity Newton's law of gravitation: Every particle in the universe attracts another particle towards them, this attraction force is called gravitation force. Two particle 'm1' and 'm2' the distance between them is 'R' and attraction force between them is 'F'.

what is escape velocity and escape energy with deeply define definition and derivation

Escape velocity When we project a body upward then after reaching a certain height, the body return back due to gravitational attraction(g) of the earth. If we go increasing the initial velocity of he body, then it returns back after reaching greater and greater height.

what is resistance

NOTE: Conductors (metals) have very little resistance while insulators (glass rubber, mica, etc.) have a large amount of resistance. Resistance is a constant term, that present where the flow of charge takes place If the potential difference (V) is 1 volt and current (I) is 1 ampere, then the Resistance (R) is 1 ohm Resistance can be found by the " BBROYGBVGW " method.

what is current, voltage, resistance and ohm's law

VOLTAGE : RESISTANCE : A resistance that opposes the flow of charge in any conductor Resistance which have a tendency to resist the flow of charge. one ohm is the equivalent of a one-kilogram meter squared per second cubed per ampere squared (1 kg times m. s. A -2.

Units and Dimension

A physical quantity is a quantity that cannot be measured or quantified. are those physical quantities that cannot be expressed in terms of other quantities -There are seven types of fundamental quantities: The physical quantities which are expressed in terms of based quantity are called derived quantities.
