Relativistic Momentum, Mass and Energy Flashcards
1
Q
What are the equations for relative mass and relative momentum?
A
m = γm0 p-> = γ * m0 * v->
2
Q
Why can nothing travel faster than light?
A
Because, using γ and the equations for mass and momentum, as v tends to c, the momentum tends to infinity, which is impossible.
3
Q
What is the equation for relativistic Force?
A
F-> = γm0a-> + γm0v->
4
Q
What is the equation for relativistic kinetic energy?
A
Ek = (γ-1)*m0c^2
5
Q
What is the equivalence of mass and energy?
A
Using relativistic mass, the mass increases the faster something goes. This means that the kinetic energy gets converted into mass. E = γmc^2
6
Q
What is the equation relating relativistic energy, momentum and mass?
A
E^2 - p^2c^2 = m0^2 * c^4 = E0^2
7
Q
What is an example of a massless particle?
A
A particle of light, the photon.
