Question

An illustration of a pendulum at 5 different positions. the central position, the equilibrium position is labeled c. the two positions on the left are labeled a and b respectively. the two positions on the right are labeled d and e respectively. all positions are equally spaced. what happens as the pendulum swings from point c to point e? check all that apply. its kinetic energy decreases. its kinetic energy increases. its kinetic energy remains the same. its potential energy decreases. its potential energy increases. its potential energy remains the same.

Answer 1

As the pendulum swings from point c to point e, its kinetic energy increases and its potential energy decreases.

As the pendulum swings from point c to point e, the kinetic energy increases and the potential energy decreases.

At point c, the pendulum is at the highest point of its swing where it has the maximum potential energy and zero kinetic energy. As it swings towards point e, the potential energy decreases and is converted into kinetic energy. At point e, the pendulum is at the lowest point of its swing where it has the maximum kinetic energy and zero potential energy.

Therefore, the correct answers are: Its kinetic energy increases and its potential energy decreases.
