Fact 1: Friction causes an object to lose energy.

Fact 2: Byproducts of friction Friction is a force acting against motion.

Given the two facts above, answer the question "Force acting against motion causes what?" with the following options: 
- Object to lose energy.
 - depress neuronal excitability
 - body temperature reduces
 - kinetic energy
 - heat production
 - heat is produced
 - heat the body
 - a lot of human deaths
