Question

Identify the kind of motion in the following case:
An electron orbiting around a nucleus.

Answer 1

1. When an electron moves around a nucleus, it generally moves with a constant speed that does not change with time.
2. In this motion, the electron moves in a circular path.
3. As per the definition of uniform circular motion, an object moves in a circular path with constant speed.
4. So we can say that this type of motion of an electron represents a uniform circular motion.

Hence, An electron orbiting around a nucleus is a uniform circular motion.
