Question

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

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

9. Rebecca climbs the ladder of a large water slide, waits her turn at the top, and then slides down the slide into a pool.

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.

Answer 4

If we don't consider friction, the total mechanical energy of the pendulum will remain constant as it swings from position A to position B. The mechanical energy of a system is the sum of its potential energy and kinetic energy. In this case, as the pendulum swings from position A (where it has maximum potential energy) to position B (where it has maximum kinetic energy), the potential energy decreases while the kinetic energy increases. Therefore, the correct answer is: potential - mechanical - kinetic.
