Question

choose the correct equation of motion​

Answer 1

Answer:

${\small{\underline{\boxed{\sf{:\implies v^2 - u^2 \: = 2gh}}}}}$

v² - u² = 2gh is a correct equation of motion and the all others aren't correct.

Additional information:

⋆ There are three equations of motion. The equations of motion are named as

◆ Velocity time relationship

◆ Position time relationship

◆ Position velocity relationship

⋆ Therefore, velocity time relationship, Position time relationship and Position velocity relationship are the three equations of motion respectively.

◆ Velocity time relationship

That's the equation,

• ${\small{\underline{\boxed{\sf{v \: = u \: + at}}}}}$

◆ Position time relationship

That's the equation,

• ${\small{\underline{\boxed{\sf{s \: = ut \: + \dfrac{1}{2} \times at^2}}}}}$

◆ Position velocity relationship

That's the equation,

• ${\small{\underline{\boxed{\sf{2as \: = v^2 - u^2}}}}}$

(Where, v denotes final velocity , u denotes initial velocity , a denotes acceleration , t denotes time , s denotes displacement or distance)
