Lesson: Relativistic EnergyPhysics
In this lesson, we will learn how to calculate the kinetic energy of objects moving at speeds large enough such that relativistic effects need to be taken into account.
Sample Question Videos
A Van de Graaff accelerator utilizes a 50.0 MV potential difference to accelerate charged particles such as protons. The kinetic energy provided by such a large potential difference is sufficiently great that relativistic effects need to be taken into account when finding the velocity of accelerated particles.
What is the velocity of a proton accelerated by such a potential?
What is the velocity of an electron accelerated by such a potential?
What is the rest energy of an electron, given its mass is kg?
Determine the difference in the rest masses of a proton and a neutron from their rest energies. Use a value of 938.3 MeV for proton rest energy and 939.6 MeV for the neutron rest energy.
