|
In order to know which of two objects is moving faster, you need to know the weight (mass) of each object in addition to the motion energy.

|
Kinetic energy is proportional to mass, so when a moving object has its mass increased by two the kinetic energy of that object increases by two. (Item uses bar graphs.)

|
Doubling the speed would have the bigger impact on increasing the kinetic energy (motion energy) of a moving object because kinetic energy increases with the square of the speed
