The door stop, acts as a spring,
pushing the door back so that it won't hit the wall.

Stapler (Spring)
The staples uses a spring and potential energy to push the staples towards the front, so they can be pushed out.

Stapler spring
This stapler uses elastic potential energy to press the staples flush against the wall of the machine. When the staples are flush the teeth of the stapler can press staples into the paper.

Electric Razor Trimmer Spring
Stapler Spring
The spring in the stapler is used to keep the staples in place by compressing and retracting depending on the number of staples in the stapler.

Elastic Hair Tie
This picture was taken in San Jacinto residence hall. It is of an elastic hair tie that uses potential energy to hold the hair in place, and out of my face.

Slinky, Spring
This slinky, when fully outstretched has Elastic potential energy. When I let go, the slinky contracts, changing that potential energy into kinetic energy.

Strength Testing Machine
This machine is locates at ECJ basement. Civil engineering students use it in compression to test concrete strength. The spring keep the flat table horizontally during the testing by absorbing the energy of uneven surface of the concrete specimen.
Restroom Hose, Spring.
A restroom Hose. When you push the hand to let the water come out and then leave it, there is a spring attached to the hand make it go back to its original place and water stops from coming out.
A Hole Puncher (Spring)
The springs on the hole puncher store potential energy in the form of compression when the hole puncher is depressed. This turns into actual work once the handle of the hole puncher is released and the kinetic energy of the spring moves the hole puncher back to its original position.

Click pens
The click pen works because of the spring.
The spring has created tension with the ballpoint of the pen, which permits it to stay exposed. When the end of the pen is clicked again, the tension is released causing the ballpoint to retract into the frame.
Pen (Spring)
When the top of a pen is clicked down, a spring is compressed (storing elastic potential energy) so that when it is clicked again it can retract the tip inti itself.
Elastic Band
My photo is of my friend's headband. The headband uses elastic potential energy, which is stored when it is stretched out, and uses the elastic potential energy to hold hair in place. This was taken in the Moore-Hill Residence hall.
Stapler, Spring
Stapler in Blanton Dormitory, 4th Floor.
The stapler here uses a spring to force the staples to the front when closed. The spring allows the stapler to easily stay loaded after stapling multiple things in a row.

Pen, Spring
The spring in this pen store the potential energy required to retract the ink cartridge when the pen is not in use.

Ukulele (Strings)
Just like a guitar or a violin, the ukulele creates elastic potential energy when its tightened strings are plucked.

Bed Springs
These springs hold up the mattress by stretching and storing potential energy as weight is applied to the mattress.

Contigo Water Bottle (Elastic)
The elastic mouth piece is connected to the underneath of the cap, all as one piece, where it holds the straw in place (the left picture shows the tube connecting the mouth piece and the straw holder). As you bend the mouth piece into a "closed" position (right picture), potential energy is stored in the elastic, as the tube is bent. When you push the button underneath the mouth piece, it pushes the white component (as seen in picture on left), releasing it from the gray catch connected to the mouth piece, and releasing kinetic energy as the mouth piece pops out into "ready-to-drink" position.

Sprayer - spring
Sprayer contains spring to when it compress it, it sprays substance easily. This photo taken at Jester East by Ginah Han.
Guitar Strings
You play the strings of a guitar by plucking them; in effect, you stretch them and create elastic potential energy, and then release them, which converts the potential energy into kinetic energy which we perceive as sound.

Bed Springs
These bed springs convert their elastic potential energy into kinetic by trying to recoil back to their original state when I lay on my bed, which keeps me from sleeping on the stuff underneath my bed.
Chip Clip
This chip clip uses the elastic potential energy in the spring to keep my Wheat Thins bag closed so my chips stay delicious. Taken in my apartment at 2400 Nueces by Emmalie Berkovsky (me).
stretchy ring, spring
This is a stretchy ring that contains rubber bands that can stretch to fit the size of anyone's finger. The rubber bands, when stretched, contain elastic potential energy. However, because of the beads fitted on the rubber bands, the impact of the rubber bands is less hurtful to the finger when they stretched out and released. Now there is no need to get your ring sized! Location: Jester 4th floor by Hareem Usmani 11:00 PM - 9/19/13
Lamp, Spring
This is the set of springs connected to a lamp. Each spring is connected to a lever arm that holds up the light of the lamp. The the pairs of springs, when placed at the proper location on the arms of the lamp, have a large enough spring constant to hold the weight, caused by the head of the lamp, upwards.

Bike, Suspension Spring
This is a spring off a mountain bike near Jester. It is not used in the traditional form of energy but used to "rob" kinetic energy and store and release it very quickly. This spring is a key part of the suspension as the force of gravity and the impacts its causes with a bike can damage or break a bike but the spring is compressed to take some of that energy, absorbing shock, and release it shortly after the impact so as to absorb the blow of an impact. Essentially, it works through impulse as well as it absorbs and releases the force over some (short) period of time.
Piano, Spring
This is the spring that is connected to the pedals on a piano. The pedal is pushed down and compresses the spring. The spring pushes the pedal back up.

Tired of being oppressed by mother nature? Not any longer! Easily stored within a purse or underwear, this action packed umbrella is spring loaded, allowing it to shoot up to a remarkable feet and a half! Become the envy of your acquaintances now with this Ella!

Bottle Sprayer, Spring
This bottle sprayer uses a spring, which must be compressed, in order for liquid to come out of the bottle. Taken on Tuesday, September 17, 2013 at the Blanton Dormitory.
Pen Clicker, Spring
The spring of the pen is attached to a clip mechanism that holds the ink tube inside the barrow when the pen's button is engaged. Another click of the main button reverses the process.
Stapler, spring
The spring in the stapler has elastic potential energy because it stores energy when it is compressed or stretched out.

Car Suspension
Suspension on my honda crv. Suspension stores energy from any impact the wheels receive in the form of a spring.
Taken at my house on 9/17/13 at around 2 PM.
Stapler--Spring
This spring holding staples in a stapler. After one staple is dispensed, the hole it created in the clip is closed by the elastic potential energy from the spring.

Trumpet Valve Spring
This is a trumpet valve used to change pitches on a trumpet. The springs compress when the valve is pressed and return the button to its original position when released.
Stapler (Spring)
The elastic potential energy is in the spring inside the stapler. When compressed to staple, the spring changes the potential energy to kinetic energy to move the stapler back up to rest position. This stapler was taken off my friend's desk while she was doing homework.
