Question

if a moving body has the variable velocity then why it has the uniform acceleration.
explain it briefly .​

Answer 1

Answer:

When an object is experiencing uniform circular motion, it is traveling in a circular path at a constant speed. If r is the radius of the path and we define the period, T, as the time it takes to make a complete circle, then the speed is given by the circumference over the period.

Answer 2

Even if a body has variable velocity, it can have uniform acceleration.

For example a body changes its velocity from 3m/s to 4m/s in 4s and 4m/s to 5m/s in the next 4s. So, clearly, the velocity is variable as it is not constant (uniform).

But acceleration in both case = 1/4 m/s².

So, even if the velocity is varying, acceleration is still constant ^_^
