Question

how does the equation v = u + at change when body starts from rest​

Answer 1

Question:

• How does the equation v = u + at change when body starts from rest?

Answer:

We know that, v = u + at, is the First equation of Motion, given by Newton.

In this equation,

• v = Final Velocity
• u = Initial Velocity
• a = acceleration
• t = time taken

Now, when a body starts from rest, it's initial velocity, u, is 0.

So, the First equation of Motion will change to,

⇒ v = u + at

⇒ v = 0 + at

⇒ v = at

Therefore, when a body starts at rest, the First equation of Motion, v = u + at, changes to v = at.

Answer 2

Answer:

v=at

Explanation: when a body starts from rest, its initial velocity , u, is 0. Therefore, when a body starts at rest , the first equation of motion, v=u+at, changes to v=
