In the equation of motion v = u + at, u represents ____________.

Correct option is A

The correct answer is (a) Initial velocity

Equation of Motion:
$v=u+at$

• $v$: Final velocity (velocity at time $t$)
• $u$: Initial velocity (velocity at the start of motion)
• $a$: Acceleration (rate of change of velocity)
• $t$: Time for which the object is in motion

This equation relates the initial velocity ($u$), acceleration ($a$), and time ($t$) to the final velocity ($v$).

Additional Information:

• Kinetic Energy (KE): The energy possessed by a body by virtue of its motion.
  KE=12mv2KE = \frac{1}{2} mv^2KE=
  ​1/2mv2

  
  where $m$ = mass of the body and $v$ = velocity of the body.​
  

• Potential Energy (PE): The energy possessed by a body by virtue of its position or configuration.
  $PE=mgh$
  where $m$ = mass of the body, $g$ = acceleration due to gravity, and $h$ = height of the body.
