Question

What are the three equations of motion?

Answer 1

The three equations of motion are:

1. First Equation of Motion: $\mathrm{v}=\mathrm{u}+\mathrm{at}$
   In the above equation $\mathrm{v}$ is the final velocity of the body, $\mathrm{u}$ is the initial velocity of the body, $\mathrm{a}$ is the acceleration of the body and $\mathrm{t}$ is the time taken in the motion
2. Second Equation of Motion: $\mathrm{s}=\mathrm{ut}+\frac{1}{2}{\mathrm{at}}^2$
   In the above equation $\mathrm{u}$ is the initial velocity of the body, $\mathrm{a}$ is the acceleration of the body, $\mathrm{t}$ is the time taken in the motion and $\mathrm{s}$ is the distance covered by the body.
3. Third Equation of Motion : ${\mathrm{v}}^2={\mathrm{u}}^2+2\mathrm{as}$
   In the above equation $\mathrm{v}$ is the final velocity of the body $\mathrm{u}$ is the initial velocity of the body, $\mathrm{a}$ is the acceleration of the body and $\mathrm{s}$ is the distance covered by the body.
