In summary, the conversation discusses the limitations of achieving high speeds of particles through non-electrical means. It is suggested that ejecting mass is the only effective way, but this results in a loss of mass. The conversation also mentions that the energy input and energy radiated must be equal in order to reach a limiting speed. Additionally, it is noted that particles can also reach high speeds through the decay of heavier particles.

Electrical means are the only way to achieve high speeds of a particle. Is it possible that you reach a limiting speed when energy radiates out as fast as it is put in? How is radiated energy accounted for in the total mass?

There really is no non-electrical way to significantly accelerate a body other than ejecting a part of the mass, in which case the mass is not constant. I don't think a compressed spring or cannon will get you up near the speed of light. The speed a body reaches when it accelerates toward the Earth from infinity is escape velocity, about 17000 mph. By the time you get near the speed of light by expelling mass you don't have any mass left.

Particle acceleration in a synchroton is limited by the energy at which energy input equals energy radiated.
Particles also achieve high speeds in decay of heavier particles.

It is indeed possible to reach a limiting speed in particle acceleration due to the conservation of energy. As particles are accelerated, they gain kinetic energy, but this energy can also be lost through radiation. As the particle approaches the speed of light, the energy loss through radiation increases, eventually reaching a point where the energy being put in is equal to the energy being lost through radiation. This is known as the limiting speed, and it is the maximum speed that a particle can reach through acceleration.

When considering the total mass of a particle, we must take into account the energy that is being radiated out. According to Einstein's famous equation E=mc², energy and mass are equivalent and can be converted into each other. So as the particle loses energy through radiation, its mass decreases accordingly. This is why particles with very high speeds, such as those approaching the speed of light, have a significantly lower mass than particles at rest.

In summary, electrical means are indeed the most efficient way to achieve high speeds in particle acceleration, and there is a limiting speed that can be reached due to energy conservation. The radiated energy is accounted for in the total mass of the particle, as it decreases as the particle gains speed. This is a fundamental concept in understanding the behavior of particles at high speeds and is crucial in the design and operation of particle accelerators.
 

1. What is particle acceleration?

Particle acceleration is the process of increasing the energy and speed of subatomic particles, such as protons or electrons, to extremely high levels using electric and magnetic fields. This is commonly done in particle accelerators, which are large machines that use electromagnetic fields to accelerate particles to nearly the speed of light.

2. How does particle acceleration work?

Particle acceleration works by using electric fields to accelerate charged particles and then using magnetic fields to steer them in a circular path. As the particles travel through the accelerator, they are constantly being pushed and pulled by these fields, which increases their energy and speed. The particles continue to accelerate until they reach a desired energy level or collide with another particle.

3. Why is it important to explore limiting speed and energy in particle acceleration?

Exploring limiting speed and energy in particle acceleration is important for understanding the fundamental laws of physics and the behavior of subatomic particles. It also has practical applications in fields such as medicine, where particle accelerators are used for cancer treatment, and in research, where they are used to study the properties of matter at high energies.

4. What are some challenges in achieving high speeds and energies in particle acceleration?

There are several challenges in achieving high speeds and energies in particle acceleration. One challenge is creating and maintaining the intense electric and magnetic fields required to accelerate particles to such high energies. Another challenge is minimizing energy loss due to collisions with gas molecules or other particles, which can cause the particles to lose speed and deviate from their intended path.

5. How do scientists study limiting speed and energy in particle acceleration?

Scientists study limiting speed and energy in particle acceleration through experiments using particle accelerators. They can also use computer simulations to model the behavior of particles and test different acceleration techniques. Additionally, researchers use theoretical models and mathematical equations to analyze and understand the complex interactions that occur in particle acceleration.
