(3) (10 pts): The work-energy theorem relates the change in kinetic energy of a particle to the work done on it by an external force: AK = W = | Fdx. a) Writing Newton's second law as F=dp/dt, show that W = S v dp and integrate by parts using the relativistic momentum to obtain E = mc²y b) Use the expression for the relativistic energy and relativistic momentum of a particle of mass m to demonstrate the important relation...
find the mathematical relationship between momentum and (mv) and kinetic energy (1/2 mv^2)
V If two particles of different masses have equal kinetic energy they also have equal momentum. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. If the momentum of a single particle is zero, its kinetic energy may not be zero. The linear momentum of an object is proportional to the mass of the object. A large force always produces a larger impulse on a body than a smaller force. If the kinetic energy of a...
a In mechanics, the energy of a moving body is called kinetic energy. If an object of mass (kilograms) is moving with a velocity v (meters per second), then the kinetic energy k( joules) is given by the equation ke we model the mass and inputs to a system (moving body) and the energy as output, then obnerve the system for while and deduce the following two rules of inference based on our observations Rule 1: IF x is small...
