Explain whether there can be any forces acting on a car moving in a straight line with constant speed.

    Thank you for using the Jiskha Homework Help Forum. Consider the weather. If there are high winds blowing against the car, that will slow forward movement. Of course, the wind could be strong and blowing from the side, making it more difficult to maintain a straight line. The flow of traffic might impede progress, as might water, oil, etc. on the road.
