Describe why using the simulation is a good method for studying projectiles. Clearly identify the error sources the simulation eliminates or minimizes. Also, run tests to determine how well the simulation represents projectile motion and identify limitations.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
