What happens to the kinetic energy of an object as its mass increases, assuming its speed remains constant?
What happens to the kinetic energy of an object as its mass increases, assuming its speed remains constant?
- Kinetic energy increases proportionally to the increase in mass. (correct)
- Kinetic energy remains constant.
- Kinetic energy decreases proportionally to the increase in mass.
- Kinetic energy increases exponentially to the increase in mass.
