If the speed of a moving object doubles, which of the following also doubles?

Question

Quizplus · Accepted Answer

Momentum is directly proportional to velocity, so if the speed (or velocity) of an object doubles, its momentum also doubles. Kinetic energy, on the other hand, is proportional to the square of the velocity, so it would quadruple if the speed doubles. Acceleration is not directly affected by changes in speed but by how quickly that speed changes over time.
