In the given graph, from 4.0 s to 8.0 s, the object is at rest because the speed is zero.
In the given graph we can deduce the following;
- at the time interval, 0 s to 3.5 s, the speed of the object = 1 cm/s
- when the time, t= 4 s, the <em>speed</em> of the object = 0 cm/s
- at the time interval, 4.0 s to 8.0 s, the<em> speed </em>of the object = 0 cm/s
When the <em>speed</em> of an object is zero (0), the object is simply at rest.
Thus, we can conclude that in the given graph, from 4.0 s to 8.0 s, the object is at rest because the speed is zero.
