Science

We are currently studying different types of variables. We are learning about pendulums. We should know the following words and content.

nPendulum is a mass hanging from a fixed point that is free to swing to and fro.

nCycle is any motion or activity that repeats itself.

nVariable is anything that you can change in an experiment that might affect the outcome.

 

nStandard is the basic procedure used in a controlled experiment, before changing any of the variables.

nControlled experiment is one in which one, and only one, variable is changed in order to assess its affect.

nA variable is anything that you can change in an experiment that might affect the outcome.

nA mass hanging from a fixed point that is free to swing to and fro is called a pendulum.

nThe number of swings of a pendulum  might be affected by mass, length, or starting position.

nMass and release position do not affect the number of swings of a pendulum; length does.

nAs the length of the pendulum increases, the number of swings decreases.
