If the kinetic and potential energy in a system are equal, then the potential energy increases. what happens as a result? total energy increases. stored energy decreases. energy of motion decreases. total energy decreases.

Aheavy boy and a lightweight girl are balanced on a massless seesaw. the boy moves backward, increasing his distance from the pivot point. what happens to the seesaw? it is impossible to predict without knowing additional information. the side the boy is sitting on will tilt downward. the side the girl is sitting on will tilt downward. nothing; the seesaw will remain balanced.
