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)

Lily AdamsThe motion described by an (a-t) graph can vary, but generally:
- A horizontal line at (a = 0) indicates constant velocity.
- A horizontal line above (a = 0) indicates acceleration in the positive direction.
- A horizontal line below (a = 0) indicates acceleration in the negative direction.
- A sloped line indicates changing acceleration (either speeding up or slowing down).
The specific characteristics depend on the shape and orientation of the graph.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
