Question

Phillip knows that it should take a ball 0.64 seconds to fall 2 meters, but when he measured the

fall, he got 0.66 seconds. What is the percent error in his experiment?

Answer 1

The percent error is the difference between the experimental and theoretical values divided by the theoretical value multiplied by 100 . So 0.66-0.64/0.66 * 100 so 0.02/0.66*100 0.03030 * 100 . The percent error is 3.0303%
