Concept of Acceleration in physics:



Let us Learn about Acceleration .Do you know what Acceleration is??? 

It is the rate of change of Velocity over time, and this may be of increase in velocity, decrease in velocity or constant.

The increase in speed or velocity is known as Acceleration, the decrease in acceleration is said as Negative acceleration, and if the velocity of a body changes equal amounts in equal time periods then it is said to uniform acceleration. 

 The acceleration caused by the gravitational attractiveness of monumental bodies in miscellaneous is said to be known as quickening due to sincerity and the, the amount of Earth's Gravitational hurrying at sea destruct (9.81 m/s2)         
     
Simple example for acceleration due to gravity is a fruit falling from the tree.

Acceleration due to gravity formula is given as:
g = GM / (R + h) 2

M= mass of the gravitating body
R= radius of the body
H= height above the surface
G= gravitational constant  9.80665 m/s2 or (32.1740 ft/s2) or (= 6.6742 × 10-11 N·m2/kg2)
