What is the primary purpose of an Atwood Machine?
To measure the acceleration due to gravity (g) precisely.
To study the relationship between force, mass, and acceleration in a system with constant velocity.
To demonstrate Newton’s Second Law by observing how masses affect acceleration.
To determine the coefficient of friction between two surfaces.
How does friction in the pulley affect the experimental results of an Atwood Machine?
It increases the measured acceleration compared to the theoretical value.
It decreases the measured acceleration compared to the theoretical value.
It does not affect the acceleration.
It causes the masses to move at a constant velocity.
If the total mass (m1 + m2) is kept constant but m1 and m2 are adjusted to increase the difference (m1 - m2), what happens to the acceleration?
The acceleration increases.
The acceleration decreases.
The acceleration remains the same.
The acceleration becomes zero.
What relationship is expected when plotting tension vs. acceleration in an Atwood Machine experiment?
Linear, with a positive slope.
Linear, with a negative slope.
Exponential growth.
No correlation.
Which of the following is NOT a significant source of error in an Atwood Machine experiment?
Air resistance acting on the masses.
Friction in the pulley.
The string has negligible mass.
Misalignment of the pulley
The Atwood Machine is conceptually similar to which real-world system?
A rocket launching into space.
An elevator moving up and down with counterweights.
A car braking on a flat road.
A pendulum swinging back and forth.
If two masses m1 and m2 (where m1 > m2) are connected by a massless string over a frictionless pulley, what is the theoretical acceleration (a) of the system?
a=m1+m2(m1−m2)g
a=m1−m2(m1+m2)g
a=m2m1g
a=g
How was initially use the Atwood machine?
To measure the acceleration of gravity.
To measure the angular acceleration of an object.
To measure the acceleration of the free-falling object.
To measure the acceleration of gravity and to measure the acceleration of the free-falling object.
What are the two unknowns that we try to find in the Atwood machine experiment?
angular acceleration (𝛼) and moment of inertia (I)
angular velocity (ω) and angular acceleration (𝛼)
acceleration of the free fall (g) and moment of inertia (I)
angular velocity (ω), angular acceleration (𝛼) and moment of inertia (I)
How many parts does the Atwood machine experiment consist of?
one
two
three
none
Is resubmission of the report allowed?
Yes, you can submit one report as many times as you want
No, therefore check your work carefully before submission. If you submit similar report, note that it will appear in Turnitin as plagiarism.
Is it permitted to include screenshots in place of graphs in your report?
Yes
No, screenshots used as graphs will not be considered during grading.
