When the car moves on road its wheel has * purely translational motion none of the above purely rotational motion rotational and translational motion?
Answers
your question is ---> when car moves on road its wheel has
1. purely translational motion
2. purely rotational motion
3. translational and rotational motion
4. none of the above
solution : option (3) is correct
when a car move on road its wheel has translational as well as rotational motion.
here ,centre of mass of wheel moves in translational motion whereas contacting points of wheel with surface rotate so, it wheel has also rotational motion.
When a car moves on a road, It's wheel performs both transnational as well as rotational motion. If you observe the motion of the centre of the wheel,you will find this motion as purely transnational while if you observe the motion of the point which is in contact with the ground is performing rotational motion.
When we see the motion of the wheel as a whole we find that it is a combination of both rotational and transnational motion.
