Subject :NSO Class : Class 9
When an ideal simple pendulum oscillates between the extreme points P and Q, there is continuous (i) of potential energy and kinetic energy. The potential energy depends on the choice of (ii) . Force acting on the bob of the pendulum is maximum at
(iii), and minimum at (iv).
| (i) | (ii) | (iii) | (iv) | |
| A | Dissipation | reference level | mid point | extremes |
| B | Dissipation | mass | mid point | extremes |
| C | Exchange | reference level | extremes | mid point |
| D | Exchange | velocity | extremes | mid point |
Ans 1:
Class : Class 9
Answer is CPotential energy depends on refernce .. nothing else
Ans 2:
Class : Class 9
yes it should be C
Ans 3:
Class : Class 10
the answer must be C) Potential energy never wins on velocity
Ans 4:
Class : Class 9
Answer is CPotential energy depends on refernce .. nothing else
