Solution

1. Periodic motion.
Periodic motion is a motion that repeats in equal intervals of time.

2. Time.
Motion can be defined as the change in the position of a body with respect to time.

3. Speed.
In a distance time graph, the slope of the graph indicates the speed of the object.

4. Time.
If a distance time graph shows a straight line parallel to time axis, then the speed of the object will be zero.

5. Non-uniform motion.
Non uniform motion is represented by a curved line in a distance time graph.
