One of the most difficult things to learn in physics is that our everyday language is not always precise enough. For instance, we might say a car is “slowing down”, but that only gives us information abouts velocity, not its acceleration. What can we say about the velocity of a car which has negative acceleration in the x-direction? a. It is slowing down. b. The x-component of its velocity is decreasing. c. The x-component of its velocity is negative. d. It is speeding up. e. The x-component of its velocity is positive. f. The x-component of its velocity is increasing.
