4. Is it possible for an object to have a non-zero
acceleration and zero velocity? Explain.
5. Newton's three laws extend beyond the realm of physics. How does
the third law relate to everyday life?
How does mass relate to energy?
How does acceleration relate to gravity?
8. How would it be possible to determine the
velocity of the earth around the sun? Is this velocity the correct velocity
of the earth through the universe?
much pressure is on your body due to the atmosphere?
Why does a balloon expand as it rises up into the sky?
What kind of waves are sound waves? Explain. Draw a picture.
What is the energy difference between a 2 kg brick lying on your foot
and one that is held one meter above your toes?
How are sound waves produced and heard---using forms of energy in your
explanation. Draw a diagram?
Why is it possible to pierce a balloon with a needle but very difficult
with your thumb? Why
is it easier to cut bread with a sharp knife rather than a dull one?
15. You place your 2 kg physics book in the back window
of a car. You want to determine the energy of the flying book as the car
is traveling 30 mph and stopping instantly? What is
the energy of the flying book if the car is traveling 60 mph? How does
this compare to a 2 kg brick one meter above your foot? Why do the airline
stewards want you to keep your carry-ons under the seat in front of you?
is the speed of sound? Why is this not constant everywhere? When is a
