What SE is stored when things are stretched?
Elastic potential energy
Elastic potential energy is stored in stretched or squashed materials.
What force is stored in a stretched spring?
Work is done when a spring is extended or compressed . Elastic potential energy is stored in the spring.
What is energy stored in a stretched or pressed object?
elastic potential energy
Potential energy due to an object’s shape is called elastic potential energy. This energy results when an elastic object is stretched or compressed. The farther the object is stretched or compressed, the greater its potential energy is.
What is EP MGH?
1. What does each of the symbols mean in this equation: EP = mgh? mass multiplied by “g” and multiplied by the change in height. 3.
What is stored in an elastic object that is unable to recover to its original shape?
When the material is stretched so it cannot immediately return to its original shape, the forces of attraction still try to restore the particles to their original positions. In this process work is done on the particles in this separation and so potential energy is stored.
What is the elastic potential energy stored in the compressed spring?
Elastic potential energy is the potential energy stored by stretching or compressing an elastic object by an external force such as the stretching of a spring. It is equal to the work done to stretch the spring which depends on the spring constant k and the distance stretched.
What is stored in the bonds of molecules?
Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules. Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released.
What is PE MGH?
Potential energy is energy an object has because of its position relative to some other object. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
What is mass times height?
The gravitational potential energy of an object is the ‘stored energy’ that the object has by being at that height. This is equivalent to its mass times the force of gravity, g (a defined constant of 9.8 m/s2) times the height of the object. Potential energy = mass x gravity x height.
What is extended elasticity?
Extension happens when an object increases in length, and compression happens when it decreases in length. The extension of an elastic object, such as a spring, is described by Hooke’s law: force = spring constant × extension. F = k e.
