Displacement time graph: gradient of a displacement time graph gives us velocity of the object
Describing displacement time graphs:
- Velocity
- direction
- reference to starting point
Car moves in opposite direction from which is started (negative displacement) when displacement is below the X axis when graph is decreasing, but still above x axis ⇒ car moves back to its original point ⇒ from which it started When this happens: state: the care is still in positive direction form starting point, but it is moving back towards starting point
 - Graph has 0 gradient → thus velocity is 0. - Displacement is constant for every second. - Car is at rest |  - Graph has constant gradient - uniform velocity (positive velocity) → away from reference point* - Displacement of cars increases 10m every second. - Moves in a positive direction from the starting point. (check) |
 - Graph has an increasing gradient - Velocity of the car is increasing (non-uniform) - Moves in a positive direction from the starting point. |  - Graph has decreasing gradient - Velocity of the car decreases - Moves in a positive direction from the starting point. |
