The units in the animation are MKS (meters, kilograms, and seconds). Each grid space represents one meter. The mass of the pendulum bob is 1 kg, and the length of the pendulum is 10 m. The acceleration of gravity is set to 9.8 m/s2. Click on a point in the animation to display the x and y coordinates. In the vector displays, the vector components are blue arrows, while the resultant vector is displayed in red.
