Science: Motion Sensors

Position vs Time – Horizontal

Horizontal

This graph shows no motion in the same position. To show this, we must stand in front of the motion sensor without moving.

Position vs Time – Increase

Increase

This graph shows the object or person moving further away from the motion sensor. To show this, we must walk further away.

Position vs Time – Decrease

Decrease

This graph shows the object or person moving closer to the motion sensor. To show this, we must walk towards the sensor, from a far position.

Position vs Time – Zig zag

Zig zag

This shows the object or person moving backward and forward in a short period of time. To show this, we must run forward and backward in a pattern.

Position vs Time – 01B (Challenge)

01B

Out aim was to match our motion (red line) with the blue line. We started off by standing 1 meter away, and staying in that position for 1 second. Then, we moved 2.4 meters away from the sensor in 2 seconds, and stopped for 3 seconds. Then we moved 80cm closer to the sensor, and stopped.

Velocity vs Time – 01E (Challenge)

01D

Our aim was to control our speed to match the red line with the blue. To show this, we moved further from the motion sensor from 0.0 to 0.5 meters per second (m/s) in 4 seconds. Then we kept the speed 0.5 m/s and moved further away. Then we moved towards the sensor in 0.4 m/s, and kept that speed for 2.5 seconds. Then we stopped.
