• This is a distance and time graph.
• When line is constant, it represents immobility, so we stay at one spot.
• When the line has a postive or inclining slope, it means moving East, in this case away from the sensor
• When the line has a negative or declining slope, it means moving towards the opposite of East - West, in this case towards the sensor.   

1. Stay at 1m for 1 second.
2. Walk 1.5m in 2 seconds (0.75 m/s) east.
3. Stay at 2.5m for 3 seconds.
4. Walk 0.75m in 1.5 seconds (0.5 m/s) west.
5. Stay at 1.75m for 2.5 s.

• This is also a distance and time graph
• Alike the first graph,line of + slope means moving East and away from the sensor.
• Vice versa, line of - slope means moving West and toward the sensor.

1. Walk from 3m east away from origin west at 1.5m in 3 s (0.5 m/s)

2. Stay at 1.5m for 1 s.

3. Walk west at 1m in 1 second (1.0m/s).

4. Stay at 0.5m for 2 s.

5. Walk east at 2.5m in 3 seconds (0.83 m/s)

 

• Different from the first two graphs, this is a velocity time graph.
• When the line is at 0, it means 0 velocity thus unmoving.
• When line is constant and +(above 0), it represents a constant velocity moving East (away from the sensor)
• When line is constant and -(below 0), it represents a constant velocity moving West (toward the sensor)

1. Stay for 2 seconds.
2. Walk east at 0.5 m/s for 3 seconds
3. Stay still for 2 seconds.
4. Walk west at 0.5 m/s for 3 seconds.

 

• This is also a velocity and time graph
• Alike the previous graph, line at 0 means 0 velocity (unmoving), constant line above or below zero means moving in East or West directions
• When line is linear (with a slope) and constant, it means a constant but gradual increase in velocity. To walk this, we have to gradually speed up in the time span

1. Run and accelerate east at 0.5 m/s in 4 seconds.

2. Walking east at 0.5 m/s for 2 seconds.

3. Walk west at 0.4 m/s for 3 seconds.

4. Stay still for 1 second.

 

• This is a distance and time graph
• Alike graph 1 & 2, line of + slope means moving east constantly. (vice versa for negative slope)
• Line of constant (horizontal line) represents 0 distance in a time span, thus 0 velocity. 

1. Walk east from 0.8m east of origin at 1m in 3.5s (0.29 m/s)

2. Stay still at 1.8m for 3.25 s.

3. Walk east at 1.4m in 2.25 s (0.62 m/s)

 

• This is a velocity and time graph
• line of constant and positive represents a constant velocity moving East (away from the sensor)
• Line of constant and negative represents a constant velocity moving West (toward the sensor)
• Sudden increase or decrease in the value of the line means a dramatic acceleration or slow down

1. Walk east at 0.35 m/s for 3 seconds.

2. Walk west 0.35 m/s for 3.5 seconds.

3. Stay still for 3.5 seconds.
