A pulley does not save energy; it merely changes the direction of the force.
A pulley on its own does not require any energy, as it's not doing anything.
A pulley in motion produces mechanical energy. This energy is a combination of potential energy (due to its position or configuration) and kinetic energy (due to its movement). The mechanical energy from a pulley can be used to perform work by lifting or moving objects.
A pulley has potential energy when it is in a raised position or under tension, ready to do work by releasing that stored energy. As the pulley moves to a lower position or relaxes tension, the potential energy is converted into other forms such as kinetic energy or heat.
A pulley does not store potential energy on its own. However, when a pulley is used in a system such as a block and tackle arrangement, potential energy can be stored in the object being lifted as work is done to raise it against gravity.
Yes, a pulley system is an example of gravitational potential energy. When you lift an object using a pulley system, you are storing potential energy in the object due to its position relative to the Earth's gravitational field.
It could have kinetic energy when the strings are being pulled and it is in operation

Energy that is put into a pulley but not used is typically converted into other forms of energy, such as heat or sound. Friction and other inefficiencies can cause some of the input energy to be lost in the system.

Be an energy champion
led lites save energy because they have less energy.
I have no idea.....stuff happens and then you save energy
A catapult does not typically use a pulley. Catapults rely on stored energy, usually from a tension mechanism like a spring or twisted ropes, to launch projectiles. The release of this stored energy propels the projectile forward without the need for a pulley system.
