Use a coordinate system with the origin at the far left and positive distances increasing to the right. P 1 - Sketch the distance (vertical axis) vs. time (horizontal axis) graph for each of the following situations when an object starting at the origin Object is at rest: d d d t t t is at rest ( v = 0) moving in the positive direction moving in the negative direction with a constant speed (+v) with a constant speed (-v) d d d t t t accelerating in the positive moving in the positive direction moving in the negative direction direction starting at rest (+a) with a constant speed greater with a constant speed greater than above than above
