RRB Group-D Model Paper 15 with answers for online practice

The first equation of motion gives the relation between initial velocity, final velocity, and time.

• First equation of motion is given as v = u + at
• Where, v = final velocity
• u = initial velocity
• a = acceleration
• t = time taken
• The first equation of motion gives the value of velocity acquired by the body at any particular point of time t.
• The second equation of motion is given as s = ut + $\mathit{½}\mathit{a}{\mathit{t}}^2$
• It gives the value of distance (s) traveled by a body at a given time t.
• Third equation of motion is given as ${\mathit{v}}^2={\mathit{u}}^2+2\mathit{a}\mathit{s}$
• This equation gives the velocity of the body in traveling the distance s.
