The energy being used to push a heavy box across the floor is mechanical energy. The person pushing the box is converting their own muscular energy into kinetic energy to move the box.
The formula used to find the amount of energy needed to lift a box is E = mgh, where E is the energy, m is the mass of the box, g is the acceleration due to gravity, and h is the height the box is lifted.
Mechanical energy is transferred through a jack-in-the-box. When the handle is turned, mechanical energy is stored in a spring. When the box opens, the stored mechanical energy is transferred to kinetic energy as the clown pops out.
When a box is picked up and placed on a shelf, the main types of energy involved are mechanical energy (kinetic energy when the box is being lifted and potential energy when it is placed on the shelf) and gravitational potential energy (due to its position in the Earth's gravitational field). Heat energy may also be generated due to friction between the box and the person picking it up or the shelf.
When lifting a box from the floor, the energy is transferred from your muscles to the box in the form of mechanical energy. The potential energy of the box increases as it is lifted against gravity. Additionally, some energy is also transferred to the surroundings in the form of heat due to friction and air resistance.

The potential energy of the box is greatest at the top of the incline because it has the highest elevation and therefore the highest gravitational potential energy.
No, the energy stored in the spring of a jack-in-the-box is potential energy due to the compression of the spring. When the spring is released, this potential energy is converted into kinetic energy and gravitational potential energy as the jack pops out of the box and moves upwards due to gravity.
A box of matches contains chemical energy stored within the match heads in the form of potential energy. When the match is ignited, the chemical bonds are broken, releasing stored energy in the form of heat and light.
The most energy efficient lighing is florescent lighting; it takes less power and energy to turn on. CFL lightbulbs are also very energy efficient and would save a lot of money. They will have an energy saver sign on the box if you are not sure. A fixture that has an energy star approved logo on the item would be the most efficient and use the least amount of energy possible. Also using energy efficient light bulbs will improve the efficiency.
When you release the lid of a jack-in-the-box, the stored potential energy in the spring is converted into kinetic energy as the spring unwinds and the box pops open. This kinetic energy is what causes the toy to pop up and the jack to spring out.
energy transfers through a jack in the box by when you turn the handle you are transferring energy into the spring and the more yu turn the handle the more energy that is being transferred to the spring to make it wotk.
