The energy required to accelerate an interstellar spaceship depends on
A) its mass only
B) its final velocity only
C) the type of fuel it uses
D) its mass and final velocity

Question

Quizplus · Accepted Answer

The energy required to accelerate an interstellar spaceship depends on its mass and final velocity according to the kinetic energy formula KE = 1/2 mv^2. The larger the mass and final velocity, the more energy is required to achieve the desired acceleration. Fuel type also plays a role in the propulsion system, but it does not directly affect the energy required for acceleration.
