why is the work done on an object moving with uinform circular motion zero
Answers
Answer:
Work done on an object is the product of force applied and the displacement covered in the direction of force applied. ... Hence, the work done in auniform circular motion is always zero. In circular motion θ is 90° hence work done by force is zero.
Answer:
In uniform circular motion work done on an object is zero, because force acting on the object is always perpendicular to its velocity and displacement.
In uniform circular motion,
i. The speed of the object is same throughout but the velocity is changing because the direction of motion of object is continuously changing.
ii. The object is accelerating, and acceleration is towards the center of circular path in which object is moving do force is also acting towards the center of the circular path i.e. perpendicular to the direction of motion.
The Path of circular motion of the object, direction of its velocity, displacement, acceleration and Force at any instant has been shown in the figure :
