Question

for freely falling object we can write newton's second equation of motion as.....

Answer 1

Answer:

mg = ma

Explanation:

Newton's second Law of motion says that force exerted by an object is directly proportional to the mass of that object if acceleration is kept constant or it is directly proportional to the acceleration if mass is constant.

Second Law

F = ma

For a free falling body, the only force will be the object's weight = mg

So,

mg = ma

cancel m on both sides

g = a

a = g

Hence acceleration is due to gravity only
