To prepare for the entrance test, 1st Year Physics Chapter 5 MCQs with Answers Circular Motion are here. This chapter is about circular or angular motion. There are concepts that are used for angular and linear motions. They have some different results. Like Angular displacement, Angular velocity, and Angular Acceleration. The relation between Angular and Linear velocities is also discussed here. There are equations of angular motion also. The most important concept here is the centripetal force. Then there is the moment of inertia. Angular Momentum is when a particle moves in such a way that its angular position changes relative to that reference axis. The real and apparent weight is an important concept that shows the weight during the body is moving and when it is at rest. In the end, there is the artificial gravity concept. Artificial Gravity is established in space by rotating the spaceship. Now solve the quiz of this chapter given below. Start preparation for your entrance test.
