Question
1. Decide whether the following statements are true or false. Place a T on the blank line if the statement is true, and place an F if the statement is false In simple harmonic motion, the restoring force does not depend on the velocity. In simple harmonie motion, the potential energy can be larger than the kinetic energy The displacement of a mass oscillating on a spring is given by x(1) = A cos[ot + ]. If the initial displacement is zero and the initial velocity is in the negative x direction, then the phase constant is /2. As we watch, a spaceship passes us in time At. The crew of the spaceship measures the passage time and finds it to be Ato, we say that Ato is the proper time for the passage and it is smaller than At. A meter stick moves at 0.95c in the direction of its length through a laboratory According to measurements taken in the laboratory, its length is 3.2m.Explanation / Answer
True (F=-kx)
True (at some instances PE can be max and KE can be zero)
True
True (Moving clocks tick faster)
False, the length from the stationary frame for 1 m should be 0.312 x 1 m = 0.312 m
