Student Name:
Access Code (located on the underside of the lid of your lab kit): AC-AQMHMN
Lab Report Format Expectations
Utilize college level grammar and formaṄng when answering text based questions.
Report all equations in a proper mathematical format, with the correct signs and symbols.
Submissions with incomplete or improperly formatted responses may be rejected.
Pre-Lab Questions
1. State Newton’s Laws in words.
First Law: An object will maintain it's state of motion unless acted upon by an external force.,
Second Law: The force on an object is equal to its mass times its acceleration, Third Law: For
every action, there is an equal and opposite reaction
2. Consider the masses in Figure 4 to the right.
Draw a Free Body Diagram for:
a. Mass 1
b. and Mass 2.
Figure 4: Free Body Diagram: 2 objects with
mass hanging on a pulley by string.
3. Apply Newton’s 2nd Law, F=ma, to write the force equations for M1 and M2. This will yield two
equations that detail the sum of forces in your free body diagram. You should get two force
equations that describe the Tension in the string (force in the up direction), weight for each
mass (force in the down direction) and accelerations for each mass (a1 and a2).
Mass One: T - M1g = m1A, Mass Two: m2g - T = M2a
