If there is no change in direction or speed but an increase in acceleration, the equation relating velocity, acceleration, and time is given by:
v = u + at
Where: v is the final velocity, u is the initial velocity (the velocity at the starting point), a is the acceleration, and t is the time.
In this case, since there is no change in speed, the initial velocity u and the final velocity v will be the same. The equation simplifies to:
v = u + at
So, the final velocity is equal to the initial velocity plus the product of acceleration and time.
