It is potential energy.
mechanical
Whatever winds the tool up - usually energy stored in your muscles.
There is chemical potential energy, heat potential energy, elastic potential, and gravitational potential energy.
It depends on spring energy or spring strength
The mechanical energy is stored in the spring as potential energy within the pullback toy and when you release it, it gets converted into kinetic energy. Hence cycle is Mechanical --- Spring (Potential)--- Kinetic
potential energy.
Compressing a spring is potential energy in a system.
Elastic energy, for example, a stretched spring.
chemical energy example, car battery, food, fuel Stored mechanical energy example, stretching or compressing a spring or rubber band
That would be the sum of kinetic energy (due to movement) and potential (elastic) energy (stored in the spring).
You can move something up, converting mechanical to potential energy (saving it). Or you can store that mechanical energy by compressing a gas, or by storing it in a spring, or by storing in as inertial forces such as running up a gyroscope.
Depends what type it is. If operated by a spring, it is elastic energy due to putting energy into the spring by mechanical winding. If operated by a battery it is the chemical energy stored in the battery.
A pogo sticks spring is compressed due to the persons weight. Potential energy is high while the kinetic energy is low at this point. when that spring then relaxes the potential energy is converted into kinetic energy due to the acceleration of the pogo stick going up in the air.
Elastic potential energy can be found when you are stretching a spring. Any kind of elastic energy can be found when you are stretching or compressing an object.
unlocking
No, the energy has to come from somewhere. In a mechanical case, like lifting a weight or compressing a spring, the work done is Force x Distance, and this goes to increasing the object's potential energy. In an electrical case, such as charging a capacitor, the energy put in is the watts of the supply times the time it applies.
In physics, elasticity is a physical property of materials which return to their original shape after they are deformed.
Spring potential energy.
