A device that changes thermal energy into mechanical energy is the automotive engine
Answer:
The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent. The closer to 100 percent a machine's efficiency is, the better it is at reducing friction
Explanation:
Answer:accelaration will decrease because forse is inversly proportional to mass.
Explanation:

- the object's mass
- the object's velocity
