Equation Of Motions MCQ - Practice Questions with Answers

There are three equations of motion

1. 1st Equation of motion or velocity-time equation

 Formula

        $V=u+a t$

V = Final velocity

u = Initial velocity

A = acceleration

             T = time

2. 2nd Equation of Position time equation

Formula

$\begin{aligned} & s=u t+\frac{1}{2} a t^2 \\ & s \rightarrow \text { Displacement } \\ & u \rightarrow \text { Initial velocity } \\ & a \rightarrow \text { acceleration } \\ & t \rightarrow \text { time }\end{aligned}$

3. 3rd Equation of Velocity –displacement equation

Formula

$$
V^2-u^2=2 a s
$$

$V \rightarrow$ Final Velocity
$s \rightarrow$ Displacement
$u \rightarrow$ Initial velocity
$a \rightarrow$ acceleration

• Displacement in the nth second

• Formula

$$
S_n=u+\frac{a}{2}(2 n-1)
$$

Where $u=$ Initial velocity
$a=$ uniform acceleration
$\mathrm{n}=n^{\text {th }}$ second
