Forces may change the shape of an object. An elastic object, such as a spring, stores elastic potential energy when stretched or squashed. The extension of an elastic object is directly proportional ...

Here is a spring mounted vertically. Also, there is a hanger for some masses on the end. Now suppose I measure the location of the bottom of the mass holder. Then I place a 250 gram mass in the holder ...

Learn how a spring stores and releases energy. Understand how work is done by spring force and how spring potential energy is calculated. #Physics #SpringForce #Energy 'Won't happen again': Stephen ...

The mass is just sitting there motionless. There is no acceleration and it is in equilibrium. What does this mean? This means that the net force in the y-direction (vertical direction) must be zero. I ...
