Domino Effect

(Fizics is phalling down)

Per

______

Name _____________________________________

Purpose:To investigate the ways in which distance, time and average speed are interrelated by finding the

speed of falling dominoes.

Procedure

REPEAT STEPS 1 - 5 THREE TIMES

Step 1: Set up 50 -100 dominos in a straight row, with equal spacing between them.

Number =

__________________

Step 2: Measure the total length of your row of dominos.

Length = __________________

__________________

Step 3: Compute the average spacing distance between dominos (length / number).

average distance between dominos =

__________________

Step 4: Measure the time it takes for your row of dominos to fall down.

time=

__________________

Step 5: Compute the average toppling speed for your row of dominos.

average speed =

Step 6: On back

What is the definition of average speed? ________________________________________________________________

____________________________________________________________________________________________________________

What are the factors that effect speed in falling dominos?_______________________________________________

____________________________________________________________________________________________________________

Why is the average speed at which the dominos fall needed, instead of using constant speed?_______________

____________________________________________________________________________________________________________

From your graph , what was the maximum toppling speed? _______________________________________________

At the maximum toppling speed of the row of dominos, how long a row of dominos would be required to make

a string that takes 1 minute to fall? Show work!!
