Swing (seat)

A swing is a seat that moves.

It hangs from chains or ropes. You can swing back and forth for fun.

Some swings are made from a tire.

You can hang a tire from a tree. Other swings use a long rope.

Small babies use bucket swings. These have holes for their legs. A parent can push them to make them move.

Some swings are for many people.

A nest swing can hold two friends. You can tilt it to move.

People have used swings for a long time. Some swings are even used for sports. It is a great way to play.

A swing is a seat that hangs from ropes or chains.

People swing back and forth for fun or to relax. You can find them at playgrounds or in your own yard.

There are many kinds of swings. A tire swing uses a whole tire hanging from a tree.

You can also use a rope swing.

Some swings are made for babies. These are called bucket swings. They have holes for legs to keep the child safe.

Some swings are for groups. A nest swing looks like a bird's nest.

It can hold more than one person. In Estonia, people play a sport called kiiking.

They use a long swing with steel bars. They try to swing in a full circle.

Swings have a very long history. Ancient Greek art shows people using swings.

In the past, some performers swung between boats on the water. Today, swings are a classic way to play and move.

A swing is a seat or a platform that hangs from chains, ropes, or bars.

People use them to move back and forth for fun or to relax. You might see them at a local playground or in a backyard garden. Some swings are even found inside homes, like the Indian oonjal. There are many different shapes and sizes to fit different people. Some are small for toddlers, while others are large enough for adults to sit on.

Moving a swing requires adding energy to keep it going. If you just sit still, air and friction will eventually slow you down. You can have a friend push you to get a good motion. You can also pump the swing by yourself using your body. While sitting, you lean back with your legs out as you swing forward. Then, you sit upright and tuck your legs as you swing back.

This motion helps you go higher and higher.

Swings have been part of human life for a very long time. We see early examples in art from ancient Greece.

A terracotta sculpture from Hagia Triada shows a woman on a swing from around 1450 BC. In China, some people believe swinging was popular during the Han dynasty. However, historians say this is actually a myth without real proof. By the Song dynasty, performers used swings in acrobatics between boats on the water.

Many special types of swings exist around the world. A tire swing can be a simple tire hanging from a tree.

A nest swing, or Giggle Basket, looks like a bird's nest and holds many people.

In Estonia, people play a sport called kiiking.

They use a long swing with steel bars to try and rotate in a full circle. There are also porch swings, which are large wooden benches for relaxing outdoors.

Swings connect simple play with the science of how things move. A swing acts like a pendulum that moves around a fixed point. To swing in a full circle, you must go very fast. Most swings use ropes or chains, which make a full loop very hard. This is because the chains must stay tight during the whole circle.

Whether it is a simple rope swing or a complex playground set, swinging is a universal way to enjoy motion.

A swing is a seat or a platform suspended from chains, ropes, or bars.

People use them to move back and forth for enjoyment or relaxation. You can find them in many places. They are common in children's playgrounds and private yards. Some people even have them inside their homes, such as the Indian oonjal. Swings are a universal way to experience rhythmic motion through play or rest.

To understand how a swing works, you can look at the physics of a pendulum. A swing oscillates, or moves back and forth, about a fixed pivot point at the top. As the rider moves downward, their gravitational potential energy converts into kinetic energy. This is the energy of motion. On the upswing, that kinetic energy turns back into potential energy.

If left alone, air resistance and friction in the pivot will eventually stop the motion. To keep swinging, you must add energy to the system. This is often done by a second person pushing or by the rider using a "pumping" motion.

There are several ways to pump a swing to increase its amplitude, which is the distance of the swing's arc. One method is driven harmonic oscillation. This happens when the rider rotates their body to create angular momentum.

This momentum is exchanged with the swing's pivot to increase kinetic energy. Another method is parametric oscillation. This occurs when the rider changes the system's center of mass. For example, a rider might crouch at the highest point and stand up at the lowest point. This change in the effective length of the pendulum helps gain energy.

Swings come in many specialized types designed for different ages and uses. For infants, bucket swings provide a secure seat with leg holes to prevent falls.

Older children might use seats made of flexible canvas, plastic, or rubberized tire treads. Tire swings are a popular variety, often made from a whole tire hanging from a tree. Some tire swings are designed for multiple children and hang flat from three or more points. Nest swings, also called Giggle Baskets, are shaped like bird nests and can carry multiple people at once.

Adults often use different styles of swings for relaxation. Porch swings are large, bench-like seats made of painted wood. They are typically mounted to a porch ceiling and can seat about three people. Canopy swings are similar but are portable and include a sunshade. There are also hammock swings, which are lightweight, removable bed-swings made of netting or canvas.

For more intense movement, tandem swings allow two people to face each other or sit back-to-back. In some parts of North America, face-to-face tandem swings are called teeter-totters.

Swinging has a very long history recorded in art and tradition. The earliest known representations are Greek artifacts. A terracotta sculpture from Hagia Triada shows a woman on a swing from the Late New Palace period, around 1450–1300 BC.

In Asia, there is a myth that swinging was popular in China during the Han dynasty. However, historians note this is not based on actual evidence. By the Song dynasty, professional acrobats used swings to move between boats on water.

In Eastern Europe, Slavic traditions have linked swinging to crop-fertility rituals.

Modern playground design has also changed over time. In the early 1900s, the playground movement brought swings into public spaces. By the mid-20th century, suburban playgrounds became very common. After the 1970s, designers began using woods and resins instead of tubular metal to improve child safety. Some people even try to turn swinging into a competitive sport. In Estonia, the sport of kiiking involves using a long swing with steel bars.

Players attempt to rotate a full 360 degrees around a central spindle.

Achieving a full 360-degree rotation is difficult on standard equipment. It is nearly impossible on ropes or chains because the swing must move at a very high velocity. The chains must maintain constant tension throughout the entire circle. If the velocity is too low, the radial gravitational force will pull the swing toward the center. This causes the trajectory to decay and results in a sudden jerk when the chain becomes taut again. Because of these physics, most swings are designed for rhythmic arcs rather than full loops.
