Question
Tomas and Gwen were trying to measure kinetic energy of a cart two ways; they mesasured the gravitational potential energy when the cart
started from rest at the top of a ramp, and they measured the kinetic energy directly when the cart reached a motion detector at the bottom of
the ramp. When they did the math, however, the two answers were not the same. The gravitational potential calculation was larger than the
direct measurement based on velocity.
Based only on this information, which of the following may be true? (In other words, which of the following is/are in keeping with these
findings?)
A. Energy is not actually conserved; it dissipates over time. The central concept behind this experiment is wrong.
B. Energy is being transformed into heat somewhere in this system, possibly as the cart wheel axles rotate.
C. The velocity measured by the motion detector is incorrect; there is a calibration error.
D. All of these may be true.
E. None of these may be true.
