PHYS 165 MODULE 3 EXAM SCRIPT
COMPREHENSIVE STUDY GUIDE
QUESTIONS WITH ACCURATE SOLUTIONS
●● On a graph of force versus time interval, how can you find the
amount of impulse exerted by the force?
A) Find the maximum y value
B) Find the maximum x value
C) Find the area under the curve
D) None of the above
Answer: C) Find the area under the curve
●● What is the product of an objects mass and velocity called
Answer: Momentum (kgm/s)
●● What is the symbol for momentum
Answer: Kgm/s
●● During a physics experiment, a raw egg is dropped from a two-story
building encased in materials that cushion the impact with the concrete
sidewalk below. This process is repeated with different materials
encasing the egg. Successful trials prevent the egg from breaking upon
, impact with the sidewalk. Assume that in all trials the mass of the
apparatus and the speed upon impact are the same. Answer the following
questions about this experiment.
True or False: The magnitude of the force exerted on the egg upon
impact with the sidewalk during all trials is the same regardless of if the
egg breaks or not.
Answer: True
●● True or False: The Impulse-Momentum Theorem states that the net
impulse exerted on a system is greater than the change in momentum of
the system.
Answer: False (its equal)
●● In what kind of system is it BEST to use the Impulse-Momentum
Theorem?
A) In a closed system only
B) In an open system only
C) In any open or closed system
D) There are no systems in which the Law of Conservation of
Momentum applies
Answer: A) In an open system only
