AP Physics  Oscillations Practice Test
Multiple Choice
Identify the choice that best completes the statement or answers the question.
1
A body oscillates with simple harmonic motion along the
x
axis. Its displacement varies with time according to the
equation
x
= 5.0 sin (
p
t
). The acceleration (in m/s
2
) of the body at
t
= 1.0 s is approximately
a. 3.5
b. 49
c. 14
d. 43
e. 4.3
2
The amplitude of a system moving with simple harmonic motion is doubled. The total energy will then be
a. 4 times larger
b. 3 times larger
c. 2 times larger
d. the same as it was
e. half as much
3 A uniform rod (mass
m
= 1.0 kg and length
L
= 2.0 m) pivoted at one end oscillates in a vertical plane as shown
below. The period of oscillation (in s) is approximately
a. 4.0
b. 1.6
c. 3.2
d. 2.3
e. 2.0
4
The figure shows a uniform rod (length
L
= 1.0 m, mass = 2.0 kg) suspended from a pivot a distance
d
= 0.25 m
above its center of mass. The angular frequency (in rad/s) for small oscillations is approximately
a. 1.0
b. 2.5
c. 1.5
d. 4.1
e. 3.5
