force of gravitation of the earth (gravity)

^{Free fall of an object and acceleration (g)}

^{→ When an object is thrown upward, it reaches certain height, then it starts falling down towar}

^{earth. It is because the earth’s gravitational force exerts on it.}

^{→ This fall under the influence of earth is called ‘free fall of an object’.}

^{→ During this free fall direction do not change but velocity continuously changes which is calle}

^{acceleration due to gravity. It is denoted by ‘g’.}

^{→ Its unit is same as acceleration m/s .}
