(b) A carrom coin moving over the carrom board.
(c) A potter's wheel
(d) A pendulum of a wall clock
(e) The skin of a drum
(f) The motion of the heart of a resting person
(g) A cricket ball rolling down the ground
gradually slows down and finally stops.
please answer of u know
Answers
The kind of motion followed in these cases are:
1. A train moving along a curved track:
This is a case of accelerated motion as the instantaneous velocity changes its direction. The train also experiences a centripetal force while making the turn.
2. A carrom coin moving over the carrom board:
This is a case of Accelerated motion as the carrom starts from rest moves with a velocity strikes another carrom and comes back to rest.
3. A potter's wheel:
This is an example of rotational motion in which the mud is rotated over a plate to shape it into a pot.
4. A pendulum of a wall clock:
This is an example of Simple Harmonic Motion in which the pendulum performs periodic oscillatory motion.
5. The skin of a drum:
This is a case of vibration motion or non-periodic Oscillatory motion.
6. The motion of the heart of a resting person:
The heart of a resting person shows periodic pumping motion.
7. A cricket ball rolling down the ground gradually slows down and finally stops:
This is an example of rolling motion; a combination of translational motion and rotational motion.
The ball starts rolling on the ground after being hit by the bat , but finally stops due to friction on the ground.
