At a specific point in its swing, a pendulum has 2J of kinetic energy and 1J of potential
energy. What is the pendulum's total mechanical energy?


Sagot :

Answer:

At its highest point (Point A) the pendulum is momentarily motionless. All of the energy in the pendulum is gravitational potential energy and there is no kinetic energy. At the lowest point (Point D) the pendulum has its greatest speed.
