AP PHYSICS 1 UNIT 6 PROGRESS CHECK (LATEST)
GUARANTEED SUCCESS
A student attaches a block to a vertical spring so that the block-spring system will
oscillate if the block-spring system is released from rest at a vertical position that is
not the system's equilibrium position. Which of the following measuring tools,
when used together, can be used to determine the spring constant of the spring?
Select two answers.
stopwatch, protractor
The students conduct experiment 2 in which the same block is connected to the
same spring on a horizontal surface. The spring is stretched a distance L2 beyond
its natural length and released from rest, allowing the block-spring system to
oscillate. Frictional forces are considered to be negligible. Which of the following
claims is correct about how the period of oscillation for the block-spring system in
experiment 2 compares with the period of oscillation for the system in experiment
1, and what evidence supports the claim?
The periods of oscillation for experiment 2 and experiment 1 are the same, because
the block and the spring used in both experiments are identical.
A student is asked to perform experiment 1, but with a spring of an unknown
spring constant. The student performs four trials of the experiment with blocks of
different mass and collects the data that are shown in the table. How should the
student graphically analyze the data in order to determine the spring constant of the
spring?
Create a graph with the period of oscillation plotted on the vertical axis and the
square root of the mass of the block plotted on the horizontal axis. Use the slope of
the best-fit line to determine the spring constant.
In one experiment, the students allow the block to oscillate after stretching the
spring a distance A. If the potential energy stored in the spring is U0, then what is
the change in kinetic energy of the block after it is released from rest and has
traveled a distance of A2 ?
3/4 U
At which of the following times does the spring exert its maximum force on the
block?
, 2s
A 4.0 kg cube is placed in a container of water. A student observes that the cube
floats. The net force exerted on the cube F represents the sum of the force due to
gravity and the force exerted on the cube by the water. A force probe is used to
measure F as a function of the cube's distance y from the bottom of the container.
The graph shows F as a function of y, where the positive direction is upward.
Which of the following statements is correct about the motion of the cube if it is
released from rest at a vertical position of y=0.05 m?
The cube will oscillate between y=0.05 m and y=0.09 m.
A student attaches a 0.6kg block to a vertical spring so that the block-spring system
will oscillate if the block-spring system released from rest at a vertical position that
is not the system's equilibrium position. The student measures the velocity of the
block as a function of time as the system oscillates, as shown in the graph. The
spring constant of the spring is most nearly
2.6
A student must use an object attached to a string to graphically determine the
gravitational field strength near Earth's surface. The student attaches the free end of
the string to the ceiling and pulls the object-string system so that the string makes
an angle of 5 degrees from the object's vertical hanging position. The student then
releases the object from rest and uses a stopwatch to measure the time it takes for
the object to make one complete oscillation. Which of the following is the next
step that will allow the student to determine the gravitational field strength?
Repeat the experiment by changing the length of the string for multiple trials.
Student X attaches an object of mass M to the end of a string of length L so that a
pendulum is constructed. Student Y attaches an object of mass M to a string of
length 4L to construct a second pendulum. Which of the following claims correctly
compares the period of Student X's pendulum with the period of Student Y's
pendulum?
The period of Student X's pendulum is half the period of Student Y's pendulum.
The gravitational field strength near Jupiter's surface is nearly 2.53 times greater
than the gravitational field strength near Earth's surface. Which of the following
claims is correct about the period of a pendulum if it oscillates near Jupiter's
surface and near Earth's surface?
