Graphs are really important for understanding how things move. They help us see the information in a clear way. Here are some key types of graphs used in motion:

1. Displacement-Time Graphs:

   • The steepness of the line shows how fast something is going. A steeper line means it's moving faster.
   • A flat (horizontal) line means the speed is steady, and a straight up-and-down line would mean the speed is incredibly fast (but that’s just a theory).

2. Velocity-Time Graphs:

   • The steepness here shows how quickly something is speeding up or slowing down. If the line goes up, it means speeding up (acceleration). If it goes down, it means slowing down (deceleration).
   • The space under the line tells us how far something has moved.

3. Acceleration-Time Graphs:

   • The area under this graph shows how much the speed has changed.

Using these graphs makes it easier to understand motion. There's also a simple formula, $v = u + at$, that helps explain how speed relates to time and acceleration in straight-line motion.
