Question

explain the meaning of following equation first question v =u+at

Answer 1

Answer:

★ $\large\bf\blue{\underline{\underline{First\ equation\ of\ motion}}}$

⠀⠀⠀⠀⠀⠀v = u + at

→ It gives velocity required by body in time t.

→ Let's consider a body having initial velocity (u). Suppose it's uniform acceleration is a so that after time t it's final velocity becomes v.

$\sf{(Acceleration = \dfrac{Final\:velocity - Initial\:velocity}{Time\:taken})}$

→ $\sf{a = \dfrac{v - u}{t}}$ $\longrightarrow\sf{at = v - u}$

→ $\large\boxed{\sf v = u + at}$

Where, v = final velocity, u = initial velocity, a = acceleration and t = time taken.

Know more:

※ There are mainly three types of equations of motion :

1. First equation of motion
2. Second equation of motion
3. Third equation of motion

※ First equation of motion → $\sf{v = u + at}$

※ Second equation of motion → $\sf{s = ut + \dfrac{1}{2}at^2}$

※ Third equation of motion → $\sf{2 as = v^2 - u^2}$
