Science-U @ Home / Pull Back Cars Experiment
Energy can transfer from one type to another. When a vehicle is pulled back, it has elastic energy. When the vehicle is released, the coil spring unwinds to convert the energy to kinetic energy, or motion. The stiffer the spring material, the more energy it stores for the same amount of compressing and winding.

Can Wind Turbines Store Energy?
The wind turbines themselves cannot store energy, but there is the capability for wind farms to store energy. When a wind turbine is working, the wind will move the turbine blades very fast. The movement of the wind turbine blades will power a generator. This generator, in turn, generates power. This power is then sent into the

What is elastic potential energy? (article) | Khan Academy
A bouncy ball, compressed at the moment it bounces off a brick wall. An object designed to store elastic potential energy will typically have a high elastic limit, however all elastic objects have a limit to the load they can sustain. When deformed beyond the elastic limit, the object will no longer return to its original shape.

6.3: ATP in Living Systems
When ATP is broken down, usually by the removal of its terminal phosphate group, energy is released. The energy is used to do work by the cell, usually by the released phosphate binding to another molecule, activating it. For example, in the mechanical work of muscle contraction, ATP supplies the energy to move the contractile muscle proteins.
