Answer
1. gravitational potential; 2. kinetic
Explanation
## Step1: Understanding the Pendulum's Energy TransferA pendulum doesn't use elastic or heat energy- so these options can be eliminated right away. The motion of the pendulum is driven by a combination of gravitational potential energy and kinetic energy, following the standard law of conservation of energy.The gravitational potential energy is at its maximum when the pendulum swing is at its highest point(where it momentarily pauses), while kinetic energy is maximized at the lowest point of the swing (the equilibrium position or the midpoint of the swing).## Step2: Setting The Altenating Energy Circle of a PendulumAs it swings or falls due to gravity, i.e. comes down, it transforms its potential energy(first choice) into kinetic energy(second choice). Therefore, the correct answer will involve these two types of energies in the proposed order.
