Item EG009004: For two objects that are traveling at the same speed, the object with more motion energy weighs more.
Object 1 and Object 2 are traveling at the same speed, but the kinetic energy (motion energy) of Object 1 is greater than the kinetic energy of Object 2. Is the mass of Object 1 greater than, less than, or the same as the mass of Object 2?
- The mass of Object 1 is greater than the mass of Object 2.
- The mass of Object 1 is less than the mass of Object 2.
- The mass of Object 1 is the same as the mass of Object 2.
- More information is needed to compare the mass of the objects.
