Question

Why during a circular motion objects tend to move outwards?

Answer 1

during a circular motion of objects they tend to move outwards due to inertia of direction which is in Newton's first law of motion...
if they move in right side around circle they tend to move left side outwards
if the object moves in left sid of circle around it, falls right side out of it...
hope you understand

Answer 2

This phenomenon is because of variable velocity. The motion of the body in a circular path even with uniform speed is with variable velocity because in a circular path, the direction of motion of the body continuously changes with time
