## What happens to the pulses as they travel through the spring?

Friction makes a pulse grow smaller in amplitude as it travels – its energy spreads out to its surroundings. The speed of a pulse is not determined by its shape, nor on how you flick the spring to create it. The speed increases as the tension is increased.

### What is a transverse wave pulse?

Transverse Pulse. A pulse where all of the particles disturbed by the pulse move perpendicular (at a right angle) to the direction in which the pulse is moving.

What waves move like a coiled spring?

In a longitudinal wave, particles of the medium vibrate in a direction that is parallel to the direction that the wave travels. You can see this in the Figure below. The person’s hand pushes and pulls on one end of the spring. The energy of this disturbance passes through the coils of the spring to the other end.

How do you describe the movement of the dot in the slinky wire when you move it sideways?

This wave is a movement of motion! This wave is called a transverse wave because the motion of the slinky is sideways to the motion along the slinky. It provides a model for waves moving along strings, for light waves(in particular linearly polarized light waves, and for seismic waves called S waves.

## What is the pulse of a spring?

The speed of a pulse, v in a long spring is given by v = τ µ where τ is the tension in the spring and μ its linear mass density. Stretch the spring tighter to increase its tension and therefore its pulse speed.

### How does the size of the pulse change as it moves along the spring?

The pulse, as defined in physics, is the transmission of energy through some type of medium, such as a rope or a coiled spring. The speed of the pulse will not change, as long as it continues to travel along in the same medium.

What is pulse in wave motion?

In physics, a pulse is a generic term describing a single disturbance that moves through a transmission medium. This medium may be vacuum (in the case of electromagnetic radiation) or matter, and may be indefinitely large or finite.

How would you describe the movement of a transverse wave?

Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.

## How do longitudinal waves move?

A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. As a sound wave moves from the lips of a speaker to the ear of a listener, particles of air vibrate back and forth in the same direction and the opposite direction of energy transport.

### What type of wave moves back and forth along the path the wave moves?

longitudinal waves
Waves in which the particles of the medium vibrate back and forth along the path of the wave are called longitudinal waves. For example, pushing together two ends of a spring causes the coils to crowd together. When you let go, a longitudinal wave is created in the spring that travels along the length of the spring.

As the Slinky moves down the steps, kinetic energy transfers from coil to coil in a longitudinal wave. The speed of the wave depends on the tension and mass of the coil. The smaller the mass, the tighter the tension, the faster energy is transferred, the faster energy moves through the Slinky.

A slinky is a pre-compressed helical spring. It was invented by Richard James in the early 1940s. It can perform a number of tricks, such as traveling down a flight of stairs, while moving end over end. It can also appear to levitate for a period of time after it has been dropped.

## What is the direction of the spring force?

As discussed above, the spring force varies in magnitude and in direction. Its magnitude can be found using Hooke’s law. Its direction is always opposite the direction of stretch and towards the equilibrium position. As the air track glider does the back and forth, the spring force ( Fspring) acts as the restoring force.

### What happens to the spring force when the glider is in position E?

By the time the glider has reached position E, it has slowed down to a momentary rest position before changing its direction and heading back towards the equilibrium position. During the glider’s motion from position E to position C, the amount that the spring is compressed decreases and the spring force decreases.

How does a spring respond to a stretching?

The spring responds to this stretching by exerting an upward force. The x and the F are in opposite directions. A final comment regarding this equation is that it works for a spring which is stretched vertically and for a spring is stretched horizontally (such as the one to be discussed below).

What is the restoring force for a mass on a spring?

The restoring force causes the vibrating object to slow down as it moves away from the equilibrium position and to speed up as it approaches the equilibrium position. It is this restoring force which is responsible for the vibration. So what is the restoring force for a mass on a spring?
