Question

The object is released from rest
under gravity at y = 0. The
equation of motion which
correctly expresses the above
situation is​

Answer 1

Answer:

the situation is free fall motion because,

Step-by-step explanation:

fre fall motion is any motion of body where gravity is only force acting upon it.

Answer 2

When an object is released from rest under gravity at y=0, gravity becomes the only force acting on it in downward direction.

Hence the motion is free fall motion and the equation is given by:

We know the second equation of motion is given by:

S = ut +1/2a$t^{2}$

Here, u = 0 and a =g

Therefore, equation becomes

S = 1/2g$t^{2}$
