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 .
