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 .
