Question

derive the 3 equations of motion a) for a freely falling object b)when the object projected in upward direction
plz give a long answer
plz derive the equations

Answer 1

Explanation:

a) freely falling body

u=0,a=+g

1.velocity-time relation

v=u+at

v=o+gt

v=gt

2. displacement-time relation

s=ut+1/2at^2

s=0×t+1/2gt^2

s=1/2gt^2

3.velocity-displacement relation

v^2-u^2=2as

v^2-0=2gh

v^2=2gh

b)when the object projected in upwards

a=-g

1.velocity-time relation

v=u+at

v=u-gt

2.displacement-time relation

s=ut+1/2at^2

s=ut-gt^2

3. velocity-displacement relation

v^2-u^2=2as

v^2-u^2=2(-g)h
