Question

equation of motio of free falling bodies ?​

Answer 1

That is to say that any object that is moving and being acted upon only be the force of gravity is said to be "in a state of free fall." Such an object will experience a downward acceleration of 9.8 m/s/s. ... Like any moving object, the motion of an object in free fall can be described by four kinematic equations.

Free Fall Formula. Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling. ... Answer: You know that gravity, g = 9.8 m/s2, and time, t = 10 sec.

Answer 2

$\huge\bf{\pink{\mid{\underline{\overline{your\: answer}}}\mid}}$

$\large{\underline{\underline{\mathbf{Equation\: of\: motion\: of\: freely\: falling\: body-}}}}$

★ When the bodies are falling under influence of gravity, the experience acceleration (g) =

${9.8ms}^{ - 2}$

★ when the body going up against the gravity, they move with retardation.

★ For motion vertically upward is (a) is replaced by (-g).

$\bold{the\: equation\: of\: motion, }$

v = u + at

Replace, a = g

v = u + gt ( when body falls downward)

v = u - gt ( when body through upward)

•:

$s = ut + \frac{1}{2} {at}^{2}$

Replace,

a = g and s = h

$= > h = ut + \frac{1}{2} {gt}^{2}$

$= > {v}^{2} - {u}^{2} = 2as$

Replace, s = h

$\bold{hence,\: Equation\: is,}$

V² - U² = 2gh
