Sagot :

Final answer:

Tractor-trailers tend to reduce speed when going downhill due to gravitational forces and the need for brake control.

True. When a tractor-trailer descends a hill, gravity acts as a force pulling it downhill, increasing its speed. To counteract this, the truck brakes need to be engaged to control the speed and prevent it from gaining too much momentum.
