Answer 1 - (i) For uniform motion of an object, its distance-time graph is a straight line with constant slope. (ii) For non-uniform motion of an object, its distance-time graph is a curved line with increasing or decreasing slope.
Answer 2 - When the slope of the distance-time graph is a straight line parallel to the time axis, the object is at the same position as time passes. That means the object is at rest.
Answer 3 - When the slope of a speed-time graph is a straight line parallel to the time axes , the object is moving with uniform speed. Since there is no change in the velocity of the object (Y-Axis value ) at any point of time (X-Axis value) , the object is said to be in uniform motion.
Answer 4 - The area occupied under the velocity-time graph is the distance travelled by the moving body. The area under a velocity-time graph is the displacement.
