Accelaration is the rate of change of velocity.It defines how velocity is chaging with respect to time.
What is Gravity Force (Fgrav): Force with which the earth, moon, or massively large object attracts another object towards itself. By meaning, this is the weight of the object.
Temperature joule; J (after J.P. Joule, 1818-1889) The derived SI unit of energy described as the amount of work done by moving an object by a distance of 1 m by applying a fo

Acceleration is nothing but it''s a change of speed of an object with respect to time. Whereas you are moving in a bike you may observe that. For example if you are moving with constant speed say 60kmph means change in velocity zero so acceleration is 0.The main thing you keep in mind that is accelaration +ve or -ve.....Because If a person slowing down from 60kmph to 50kmph,here change in velocity is 10 so acceleration is 10 but it is negative(decreasing)..Similar way he person again come to 60kmph from50kmph..Obviously his acceleration is 10.but it is in increasing so we say positive or increasing acceleration....
