A graph paper is situated on a board. Near the graph paper a spring is placed. A pencil is attached to the end of the spring. The pencil is free to move on the graph paper. A stone of mass 50g m is placed 1 m above the spring. [Spring constant `k= 98N/m`] . the energy possessed by the stone due to its height is called `cdots`.

A graph paper is situated on a board as shown in figure. Near the graph paper a spring is placed. A pencil attached to the end of the spring as shown in figure. The pencil is free to move on the graph paper. A stone of mass 50g m is placed 1 m above the spring. [Spring constant k= 98N/m ]. What will happen to the length of mark if spring having smaller spring constant is used? Justify.

A toy gun with a spring compressor 3 cm is used to project a stone of mass 50 gm to a height of 10m. What is the potential energy of spring?

A toy gun with a spring compressor 3 cm is used to project a stone of mass 50 gm to a height of 10m. Find out the physical constant associated with the spring.

A toy gun with a spring compressor 3 cm is used to project a stone of mass 50 gm to a height of 10m. How much it should be compressed to throw the stone to a height 5m?

A spring of spring constant 'k' is used to suspend a mass 'm' at its free end while the other end of the spring is rigidly fixed. If this system is taken into outer space then what happens to its period?Why?
