Question
Tie a heavy metal washer to one end of a string, hold the string by the other end, and whirl it in a horizontal circle above your head. Pay close attention to where your hand is and to where the washer is as you speed up the rotation. Ignore air resistance.
1)As you speed up the rotation, what force is responsible for the acceleration of the washer?
2)Is there a tangential component to this acceleration? A radial component?
b- The acceleration has neither radial nor tangential component.
c- The acceleration has only a tangential component.
d-The acceleration has only a radial component.
a- tensile force b- gravitational forceExplanation / Answer
The string as moves above our head has tensile force as this force is responsible to pull something and gravitational forces pulls body towards earth.
As the speed is varying the object has both tangential and radial acceleration.
