Question

4. Look at the diagram and answer the following questions:
a) Name the kind of motion of the stone.
Thread
Stone
b) Is this an example of accelerated motion? Why?
c) Name the force that keeps the stone in its path.​

Answer 1

Answer:

a) circular motion

b) Yes centripetal acceleration is always acting

c) tension force

Answer 2

Answer:

a ) Circular motion.

b ) yes.

c ) Centripetal force.

Explanation:

a.) Both Stone and thread are in circular motion.

b.) Yes, this is an example of accelerated motion because there is a continuous change in the direction of the stone. So, the velocity of stone changes when the direction of the stone changes and the change in velocity at per unit time is called acceleration. Therefore, this an example is of accelerated motion.

c.) Centripetal forces keeps the stone moving in its path.
