A girl bends to touch her toes. is the motion of the her head an example of uniform motion or accelerated motion? explain your answer
Answers
Answer:
The motion of the head of the girl while touching her toe is an example of accelereted motion because (i) The direction of her head is a circular path. So, The direction of velocity is always changing and so the velocity always changing. (i.e - The velocity can never be constant). Since, the velocity is changing.
Explanation:
The motion of the head of the girl while touching her toe is an example of accelereted motion because (i) The direction of her head is a circular path. So, The direction of velocity is always changing and so the velocity always changing. (i.e - The velocity can never be constant). Since, the velocity is changing. So, there is an acceleration & hence, it is an example of accelereted motion.
(ii) Also because, Before bending her head, The speed of her head is zero and when she starts bending her head, the speed of her head is gradually increasing and finally after touching her toes, the speed of her head is again zero. So, This conclude that the speed is continuously changing. (i.e The speed can never be constant). Since, the speed is changing. So, there is an acceleration. So, it is an example of accelereted motion.
It is not uniform motion because we observe that neither its velocity is constant nor its speed is constant.
