For this which of the statements is true (a) the laws of motion are valid only for truly point size objects (b) the laws of motion are valid for all bodies which move distance much larger than their own sizes (c) the laws of motion are valid for all bodies irrespective of their sizes and the distance they move (d) the laws of motion are valid for large bodies even if they move distance much less than their sizes Q2. Which of the following in a closest example of motion in one dimension (a) a train moving on a railway track (b) a boat sailing on a lake over distances small compared to earth radius (c) a billiard ball in motion (d) earth moving around the see Q3. The position-time graph for an object is shown below. This is an example of (a) motion in one dimension (b) motion in two dimensions (c) motion in three dimensions (d) stationary object x x 0 True Q4. Which of the graphs (velocity-time) represents uniform motion (a) velocity (v) time(t) (b) (v) (t) (c) (v) (t) (d) (v) (t) Q5. A body is uniform motion in one dimension moves from a position x at time t to another position at time t . Which of the statements is wrong for this motion. (a) the actual distance covered in time t to t is the magnitude of displacement (b) the velocity calculated by making any choices for t and t always gives the same result (c) a larger value of the difference t - t will give a small value of the velocity because velocity is obtained by dividing by t - t (d) a larger value of x - x will give larger value of the velocity. Q6. For a body in uniform motion in one dimension, which of the following statements is not true (a) the body has constant speed (b) the body has constant velocity (c) the body has constant acceleration (d) the body moves equal distance in equal time intervals. Q7. Which of the graphs (position - time) represents uniform motion in one dimension (a) position (x) time (t) (b) x t (c) x t (d) x t
