MOTION CURATION PROJECT

How do we measure and describe motion?

The speed of a running pet

PROCEDURE:

• I mark the spot where my dog will start and stop running.
• I make my dog sit, and I tell him to stay.
• Then I call him with a treat, while timing him.
• I stop the timer, and give him the treat.
• I repeat this experiment 2 more times.

Distance: 4 meters
1- 4.0 seconds
2- 3.9 seconds
3- 4.6 seconds
Average: 4.16seconds
Speed: 4m ➗ 4.16s = 1.04 m/s

The rising water level in a sink.

PROCEDURE:

• I plug the drain of the sink.
• Then I run the water at medium speed.
• I start the timer right after I turn on the water.
• I wait until the sink is filled with water.
• Then I stop the timer, and repeat the experiment 2 more times.

Distance: 10cm (upwards.)
1- 1 minute and 20 seconds
2- 1 minute and 25 seconds
3- 1 minute and 16 seconds
Average: 1.20 seconds
10cm ➗ 1.20s = 8.3s/cm

The speed of a dog's wagging tail.

PROCEDURE:

• I measure my dog's tail in centimeters.
• Then Start the timer to see how long it takes for his tail to go in 1/2 circle.
• Then stop once I it has.
• Then I repeat the experiment 2 more times.

Distance: 1/2 circle (12cm)
1- 16 seconds
2- 15 seconds
3- 15 seconds
Average: 15.3 seconds
15.3s➗12cm = 0.06 s/ wag of tail
