Answer: The first equation of motion is denoted by v = u + at.

The first equation of motion is used to represent the relation between "velocity and time". With the help of the first equation of motion, one can find final velocity, initial velocity, acceleration and time.

Summary:

What is the first equation of motion?

The first equation of motion is denoted by v = u + at. When the body is accelerating then ‘a’ is positive and when it is negative when the body is not accelerating.
