# Could you help me describe the motion below a-t graph (acceleration vs. time)?

## How would you go about describing the motion of each slope? (*Assume [N] is +ve)

1. An object has acceleration $a = 0 c m {s}^{-} 2$ at time $t = 0 s$
2. We observe that its acceleration changes linearly to $- 2 c m {s}^{-} 2$ in the next $1 s$.
3. For next $1 s$, from $t = 1 s \text{ to } t = 2 s$, the acceleration increases linearly to $1 c m {s}^{-} 2$.
4. From $t = 2 s \text{ to } t = 5 s$ the object moves with constant acceleration of $1 c m {s}^{-} 2$.
5. For next $1 s$, from $t = 5 s \text{ to } t = 6 s$, the acceleration decreases linearly to $0 c m {s}^{-} 2$
6. The object continues with $0$ acceleration for next $1 s$, from $t = 6 s \text{ to } t = 7 s$,
