Concisely answer questions within 3 sentences. Box or highlight your answers. Use your own
sketches to help you illustrate your responses if needed.
1. What do specific heat, thermal expansion
coefficient, and Hooke’s constant have in
common? How do they relate to
understanding the properties of objects
described by Newton’s 1st law?
2. Refer to figure 1. The force vs. displacement
profile of three different springs are
highlighted. Calculate the spring constant
(i.e. Hooke’s constant) for each spring.
Which spring is the strongest (i.e. will pull
the hardest on an object)?
3. Refer to figure 1. For the blue line (i.e.
second spring), calculate the total amount of
work done based on the force vs.
displacement profile. What would be the
maximum kinetic energy and maximum
velocity of a block attached to this spring?
What would be the mass of said block and
angular frequency of this block?
4. Refer to table 1: Calculate the amount of
heat needed to raise the temperature by 2.0
oC of a 10.0 kg block of ice and a 10.0 kg
lock of lead. Why are the amounts of
energy different between the two blocks?
5. Refer to tables 2 and 3: A small gold rod of
length 0.125 m is heated up to the point that
the rod increases in length to 0.126 m. Does
it melt if heated from 0oC?
Figure 1: Force vs displacement plots of three
different springs. Frequency for an object attached to
the 2nd spring is 2.0 Hz.
