The net displacement of a particle in a constant uniform field equals one-half this quantity multiplied by time squared. For 10 points each:
[10e] Name this quantity that multiplies mass to yield force in Newton’s second law.
ANSWER: linear acceleration [prompt on a]
[10h] In the absence of an external field, the average magnitude of the displacement of a particle that freely diffuses according to a random walk scales with this function of the diffusion time.
ANSWER: square root of time [or time to the one-half power; prompt on root of time]
[10m] For a particle in a field whose potential is given by this statement, the displacement evolves sinusoidally with time. This statement can be given as “the second time derivative of x equals negative k x over m.”
