the image shows a pendulum that is released from rest at point a. which energy transformation is correct? from a to c, kinetic energy is transformed into gravitational potential energy. from c to d, kinetic energy is transformed into gravitational potential energy. from c to e, gravitational potential energy is transformed into kinetic energy. from d to e, gravitational potential energy is transformed into kinetic energy.
Answer
Brief Explanations:
- Recall the principles of energy transformation in a pendulum: At the highest - point (like A and E), the pendulum has maximum gravitational potential energy and zero kinetic energy (since it is at rest). At the lowest - point (like C), it has maximum kinetic energy and minimum gravitational potential energy.
- Analyze each option:
- From A to C, gravitational potential energy is transformed into kinetic energy as the pendulum moves downwards.
- From C to D, kinetic energy is transformed into gravitational potential energy as the pendulum moves upwards.
- From C to E, kinetic energy is transformed into gravitational potential energy as the pendulum moves upwards.
- From D to E, kinetic energy is transformed into gravitational potential energy as the pendulum moves upwards.
Answer:
From C to D, kinetic energy is transformed into gravitational potential energy.
