Which statement CORRECTLY describes the energy transformation as the pendulum swings from point A to point B? A

The kinetic energy of the pendulum is highest when the washer is at point A and decreases to a minimum at point B.

B

The potential energy of the pendulum is highest when the washer is at point A and decreases to a minimum at point B.

C

The kinetic energy of the pendulum remains the same as it moves between the two points labeled A.

D

The potential energy of the pendulum remains the same as it moves between the two points labeled A.

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
