What is the magnitude of the change in potential energy of the block-spring
system when it travels from its lowest vertical position to its highest vertical
position?
1/2k0(L1+L2)^2
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.
The students must conduct an experiment to determine the magnitude of the
force exerted on the block when the block is at a position of A2, where A is the
amplitude of oscillation for the block-spring system. For each trial, the students
attach blocks of different mass m to the spring, stretch the spring a known
distance A, release the system from rest, measure the period of oscillation T, and
then measure the maximum velocity v of the system. How should students use a
graph to determine the magnitude of the force under consideration?
Determine the magnitude of the slope of the best-fit line of T^2 as a function of m.
Multiply the result by A/2.
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
