01
Spring scales are used to measure the net force applied to an object; a sonic
motion detector is used to measure the object's resulting acceleration. A graph is constructed with the net force on the vertical axis and the acceleration on thehorizontal axis. Which of the following quantities is directly measured using the slope of this graph?
(A) Gravitational mass (B) Weight
(C) Velocity
(D) Inertial mass

D—The relevant equation connecting force and mass is F = ma. The slope is the vertical axis divided by the horizontal axis, or F/a = m. So the slope is mass.

4. B—The dots divide the 1-meter distance into five parts. In the time between dots, the cart travels 0.2 m. The time between dots is 0.05 s. At constant speed, the speed is given by distance/time: 0.20 m/0.05 s = 4 m/s.
5. D

C—The kinetic energy (Image) change can be determined by knowing the mass and the speed change.
04
AP物理1考试选择题解析:
A—On this graph, the multiplication of the axes means to take the area under the graph. The area of a triangle is ½(base)(height). That’s ½(5 N)(2 s) = 5 N·s.
05
AP物理1考试选择题解析:
B—If friction and air resistance are negligible, a mass on a spring oscillates about the equilibrium position, reaching the same maximum distance above and below. In this case, since the mass doesn’t get all the way to position A at the top, mechanical energy was lost (to friction or air resistance or some nonconservative force). Thus, without some external energy input, the mass won’t reach its maximum position at the bottom, either—at the bottom, it will have no kinetic energy, so all the energy will be potential, and we’ve already established that some total mechanical energy was lost.
