Question

When driving on a straight flat freeway, you keep your foot on the accelerator to keep the car in motion at constant velocity. Which of the following represents this situation? The net force on the car

A. is in the forward direction
B. depends on the car’s speed
C. is toward the rear
D. depends on the car’s engine
E. is zero

Answer 1

Answer: E. is zero

Explanation: According to Newton's first law of motion, any object moving at constant velocity has no net external force acting upon it, which means that the sum of the forces acting on the object must be zero. Given that the car is maintaining a constant velocity, we can say that there is no net force acting on the car.
