Question

    The distance- time graph for a body moving at uniform

    speed is?
    A A hyperbola Correct Answer Incorrect Answer
    B A straight line Correct Answer Incorrect Answer
    C A parabola Correct Answer Incorrect Answer
    D An ellipse Correct Answer Incorrect Answer

    Solution

    A uniform motion is defined as the one where speed does not change with time. Hence, only distance and time changes. We know that speed= distance/time. Since, speed remains constant, therefore we can conclude that distance and time are directly proportional to each other. Hence, the graph between distance and time is a straight line. Hence, option B is correct.
