Question

An elastic band is hung on a hook and a mass is hung over the lower end. What will happen to the elastic band when the mass is released?

1) The elastic band will stretch and the mass will fall down
2) The elastic band will contract and the mass will fall down
3) The elastic band will remain unchanged and the mass will fall down
4) The elastic band will break and the mass will fall down

Answer 1

When the mass is released, the elastic band will stretch and the mass will fall down.

Step-by-step explanation:

When the mass is released, the elastic band will stretch and the mass will fall down. This is because the elastic band will stretch to accommodate the weight of the mass, creating potential energy in the band. Once the band stretches to its maximum limit, it will start to contract, pulling the mass downward.
