Question

A rocket takes off from the earth and continues to move in a circular orbit with the thrusters on. What can be said about the angular velocity of the rocket?

(a) It increases

(b) It decreases

(c) It remains constant

(d) It changes abruptly

I got this question in quiz.

I'd like to ask this question from Non-Uniform Circular Motion topic in division Laws of Motion of Physics – Class 11

Answer 1

The correct answer is (a) It increases

The explanation: When the rocket is in the orbit with the thrusters on, there is a tangential force that the rocket experiences. This force will result in increasing the tangential velocity. Since the angular velocity is directly proportional to the tangential velocity, the angular velocity will also increase.
