- When a car moves along the highway at constant
velocity, the net force on it is zero. Why, then, do
you continue running your engine? (Hint: How
does friction enter into your answer?)

Final answer:

Friction and net forces play a key role in the engine running when a car moves at a constant velocity.


Explanation:

Friction plays a crucial role in why engines continue running when a car moves at a constant velocity on the highway. Despite the net force on the car being zero, the engine needs to overcome frictional forces to maintain the constant velocity. For a car to accelerate, the friction force must be greater than the drag force, providing the necessary net force for acceleration.
