If we don't consider friction, what happens to the total mechanical energy as the pendulum swings from position A to position B?

Question

O potential - kinetic - potential
O kinetic - mechanical- potential
© kinetic - potential - kinetic
• potential - mechanical - kinetic

Answer 1

The correct answer is: potential - mechanical - kinetic.

Answer 2

Which answer best describes the energy changes during her time on the slide? (1 point)
O potential - kinetic - potential
O kinetic - mechanical- potential
© kinetic - potential - kinetic
• potential - mechanical - kinetic

Answer 3

The correct answer is: potential - kinetic - potential.
