could someone PLEASEE help me? Ive procrastinated and i'm really desperate... I'm supposed to teach the class about "relativistic momentum and mass" in terms of special theory of relativeity. i looked up infomation on google, but i don't understnad because its mostly university level. could someone please explain the concepts to me?

This is not a subject to put off. Few understand it.
Notice from the link, that "mass" increases as speed gets close to the speed of light. In theory, momentum and mass are infinite at the speed of light. Think of mass as a quality resisting changes in motion, and as one moves closer to the speed of light, the resistance becomes infinite.
I am wondering what you are going to teach the class.

Of course, I'd be happy to help you understand the concepts of relativistic momentum and mass in the context of the special theory of relativity.
Relativistic momentum and mass are the concepts that describe how the motion and mass of an object change as it approaches the speed of light. In classical physics, momentum is defined as the product of an object's mass and its velocity. However, according to the special theory of relativity, the relationship between momentum, mass, and velocity is modified at high speeds.
In terms of relativistic momentum, it is given by the equation: p = γ * m * v, where p is the relativistic momentum, m is the rest mass of the object, v is its velocity, and γ (gamma) is the Lorentz factor, which is defined as γ = 1 / sqrt(1 - (v^2 / c^2)), where c is the speed of light in a vacuum.
The Lorentz factor plays a crucial role in relativistic momentum because it accounts for the increase in mass as an object's velocity approaches the speed of light. This increase in mass is often referred to as relativistic mass, which is given by m = γ * m_0, where m_0 is the rest mass of the object. As the velocity of an object approaches c, γ approaches infinity, and thus, the relativistic mass also approaches infinity. This leads to the understanding that it takes an infinite amount of energy to accelerate an object with mass to the speed of light.
Now, regarding the link you provided (http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/relmom.html), it is a great resource to understand and explore the details of relativistic momentum and mass. However, as you mentioned, it might be at a more advanced or university level. My suggestion to understand the concepts better is to break them down step by step.
Start by understanding the basics of special relativity, including the Lorentz factor and the consequences of time dilation and length contraction. Then, delve into the concept of relativistic mass and how it affects momentum. It may be helpful to think of mass as a measure of inertia or resistance to motion, and as an object accelerates, its resistance to motion increases infinitely as it approaches the speed of light.
To prepare for your class, I recommend studying examples and working through practice problems to reinforce your understanding. Additionally, breaking down the information into simpler terms and creating diagrams or visual aids can also help convey the concepts to your students more effectively.
Remember, it's essential to present the material in a way that students at your level can understand. Focus on the core ideas and provide real-world examples or analogies that make the concept of relativistic momentum and mass more relatable. Good luck with your class!
