Mini-Quiz: Weak Equivalence Principle of Gravitation

1. According to the Weak Equivalence Principle, does the heavier object fall faster?

   Yes, heavy objects fall much faster than lighter weight objectsSorry, not correct. Try another button. It is uncertain since no one has ever tried to compare the rate of fall of two objectsGood try, but not right. Select another answer. Weight or mass difference does not affect the rate the objects fallCorrect. You know about the weak equivalence principle.

2. What is a requirement for the Weak Equivalence Principle?

   Falling objects must be close to the mass of the EarthOops! Wrong answer. Re-read the question and try again. The objects must fall freely without external forcesThat is Correct. You must be a genius! The force of gravity must be very weakSorry, not correct. Try another button.

3. What comes into effect when the mass is equal to the attracting object?

   The weak principle does not hold since they both move toward their center of massCorrect. You know about the weak equivalence principle. The velocity is doubledGood try, but not right. Select another answer. The objects still fall at the same rate no matter what their masses areCorrect. You know about the weak equivalence principle.
