Phys 261 Final exam with
correct answers graded
A+
Experiment 1: Excel - correct answer-The purpose of this experiment is to teach you a few basic things
about using EXCEL 2010 to plot and analyze data in the Physics lab.
Experiment 2:Uncertainty in Measurements - correct answer-The purpose of this lab is to learn how to
estimate uncertainty in measurements, how to do error propagation, and why it is important to
understand the uncertainty in measurements.
Experiment 3:Position, Velocity and Acceleration - correct answer-The purpose of this lab is to study the
position, velocity, and acceleration of a body that is acted on by a constant force.
Experiment 4: Momentum and Drag - correct answer-The purpose of this lab is to observe the drag
force and conservation of momentum.
Experiment 5: Centripetal Motion - correct answer-The purpose of this lab is to measure an object
undergoing centripetal acceleration
Experiment 6: The Pendulum and g - correct answer-The purpose of this experiment is to determine the
dependence of the oscillation period of a pendulum on the pendulum's length and mass.
Experiment 7: Forced Harmonic Motion - correct answer-The purpose of this lab is to examine the
amplitude, resonant frequency, damping time, quality factor, and phase shift of a driven mass-and-
spring oscillator.
Experiment 8: Waves on a String - correct answer-The purpose of this lab is to examine waves on a
string.
