the image shows a pendulum that is released from at point a. which pair of labels is correct? a: maximum…

Answer:

C. A: Maximum gravitational potential energy, C: Maximum kinetic energy

Explanation:

Step1: Understand energy at extreme - top position

At point A (highest position), the pendulum is at rest momentarily. Its height is maximum. Gravitational potential energy (U = mgh) (where (m) is mass, (g) is acceleration due to gravity and (h) is height). So it has maximum gravitational potential energy.

Step2: Understand energy at lowest position

At point C (lowest position), the pendulum has maximum speed. Kinetic energy (K=\frac{1}{2}mv^{2}) (where (v) is velocity). Since speed is maximum here, it has maximum kinetic energy.
