Question

Write the three equation of motion of freely falling body when its v=v u=0 and a=g.solved derived equaton

Answer 1

Answer:

The formula for free fall:

Imagine an object body is falling freely for time t seconds, with final velocity v, from a height h, due to gravity g. It will follow the following equations of motion as:

h=  1/2 gt^2

v²= 2gh

v=gt

h Height traveled

v Final velocity

g Acceleration due to gravity

t Time taken

These equations can be derived from the usual equations of motions as given below, by substituting

initial velocity u=0,

distance traveled s=h and

acceleration, a=g.

We can see it as follows:

s= 1/2ut+ at^2

v² =u²+ 2as

v=u+at

Freefall is the autonomous phenomena of the body with some mass. It only depends on height from the surface and the time period for which the body is flung.

Explanation:

Answer 2

Three equation of motion for free falling body is nothing, 'a' is replaced by 'g' and 's' is replaced by 'h'.....

》First equation- v = u + gt

》Second equation- h = ut + 1/2 gt^2

》Third equation - V^2 = u^2 + 2gs

Free fall is happend when only gravity

works on body and no other force....
