An object moves by an observer at 0.600c.The total energy of the object will be what factor times that of the rest energy?
A) 1.25
B) 0.970
C) 1.15
D) 0.600

Question

Quizplus · Accepted Answer

The total energy of an object moving at a velocity v is given by the equation E = γE₀, where γ is the Lorentz factor, γ = 1/√(1-v²/c²). For v = 0.600c, γ = 1/√(1-(0.600)²) = 1.25. Thus, the total energy is 1.25 times the rest energy.
