Question

state and prove 1st equation of motion.​

Answer 1

Answer:

The first equation of motion is:

v = u + at

where, v is the final velocity, u is the initial velocity, a is the acceleration and t is time taken.

Explanation:

As we know that,

The formula of Acceleration = (v - u ) /t

a = (v - u) / t

=> at = v - u

=> u + at = v

[ .°. v = u + at ]

or

Let us consider a body moving with uniform acceleration in a straight line.

The initial velocity is = u

The velocity at the end of one second is = u + a

The velocity at the end of two seconds is = u + 2a

The velocity at the end of three seconds is = u + 3a

The velocity at the end of t seconds is = u + ta

Therefore, the velocity at the end of "t" seconds that means the final velocity is equal to = u + at

.°. v = u + at
