Question

write the expression for acceleration in a circular uniform motion in vector form​

Answer 1

We call the acceleration of an object moving in uniform circular motion the centripetal acceleration ac because centripetal means center seeking. ... Because a c = Δ v / Δ t a c = Δ v / Δ t , the acceleration is also toward the center, so ac is called centripetal acceleration.

Answer 2

Answer:

Centripetal acceleration always points toward the center of rotation and has magnitude aC=v2/r. a C = v 2 / r . ... The total acceleration is the vector sum of tangential and centripetal accelerations. An object executing uniform circular motion can be described with equations of motion.
