Automatic wrist watches get energy from the various movements of our hand. These watches contain a rotor that rotates with the movement of the wearer’s wrist. This movement winds the mainspring, storing energy that powers the watch’s movement and functions ...
When we pull up a bucket of water from a well, we feel that the bucket has become lighter above the surface of the water. As the bucket rises, water drips off, reducing its overall weight. This sensation occurs due ...
Weightlessness occurs in the zero state of gravity. In this condition, objects experience apparent weightlessness because there is no gravitational force acting on them. Weightlessness can be simulated in environments such as space, where objects and individuals float freely due ...
Steel is the most elastic among the options provided. Elasticity refers to a material’s ability to regain its original shape after deformation. Steel exhibits high elasticity, making it ideal for structural applications where resilience and durability are crucial.
