Motion graphs, like distance-time and velocity-time graphs, are helpful tools to figure out where moving objects will be in the future.

1. Distance-Time Graphs: When we see a straight line on this graph, it means the object is moving at a constant speed. We can use this simple formula:
   $d = vt$
   Here, $d$ stands for distance, $v$ means velocity (or speed), and $t$ is time.

2. Velocity-Time Graphs: On this type of graph, the space under the line shows how far the object has moved.

3. Acceleration: If the speed is changing at a steady rate, we can find out the future speed using this formula:
   $v = u + at$
   In this case, $u$ is the starting speed, $a$ is the rate of acceleration (how quickly it’s speeding up), and $t$ is time.

These graphs make it easier to predict where an object will be in the future.
