Use the drop-down menus to explain the procedure (from image) that will BEST allow the student to complete measurements for the investigation.

Procedure ​ ​ (a)   should be used. In this procedure, the moving pendulum will demonstrate transforming ​ ​ (b)  

• W
• potential energy into kinetic
• X
• kinetic energy into potential

Answer explanation

“W” is the correct response for the first drop-down menu because this is a fair test that does not risk

varying starting forces. “Potential energy into kinetic” (energy) is the correct response for the second

drop-down menu because raising a weight such as a pendulum to a height gives it potential energy,

which is then transformed into kinetic energy as the pendulum falls. Pushing a pendulum would just give

it kinetic energy to start with, which would not demonstrate a relationship between potential and kinetic

energy.
