Oscillations of a loaded spring

Questions

1. Is the gravitational force on the block constant?

2. Is the spring force acting on the block constant?

3. Identify the pairs of quantities ( from displacement, velocity, acceleration, spring force and gravitational force ) that are always in the same direction during the oscillation.

4. Identify the pairs of quantities ( from displacement, velocity, acceleration, spring force and gravitational force ) that are always in opposite directions during the oscillation.

5. What happens to frequency of oscillation when mass is increased for a fixed value of spring constant?

6. What happens to time period of oscillation when spring constant is decreased for a fixed value of mass of the load?

7. Is acceleration of the block constant in (a) magnitude (b) direction?

8. At the extreme positions ( at y = +A ) is the net force acting on the block zero?

9. At the mean position ( at y = 0 ) is the net force acting on the block zero?

Note :

Questions given above may be visualized and solved using the simulations, obtaining a mathematical solution is to be always treated as the final answer.

Such a mathematical solution implies that you are able to understand and apply the concept.
