What did Alexis measure when Miranda swung the pendulum?

• The height of the swing

• The number of times it hit the chair

• The time it took to complete one swing

• The length of the string

What did the girls discover about the time of one swing when they changed the distance of the swing?

• It got faster with longer swings

• It took more time with shorter swings

• The time stayed the same

• The pendulum stopped moving

• Heavier weights swing faster

• Lighter weights swing slower

• Both heavy and light weights swing the same number of times in equal time

• Weight stops the pendulum from swinging
