What is the equilibrium position of an
Why is the velocity greatest at the equilibrium
why not before it?
why not beyond it?
What is damping (and what causes it)?
What is the restoring force? What
is it proportional to?
What is simple harmonic motion?
What is Hooke’s law? (Give the full names
of the terms.)
What unit(s) is a spring constant given
Give five examples of springs. Rank them in increasing order of their spring constants.
How much force can a slingshot produce on a rock if it is pulled back 0.23 m and it has a spring constant of 150 N/m on each of the two rubber bands?
What is the spring constant of a spring
that stretches 0.17 m when a load of 57 N is placed on it?
When does a spring have the greatest elastic
Why is Earth’s rotation periodic but not
Give four examples of pendulums (or things
exhibiting motion like a pendulum).
What is a bob?
What three things do we disregard when
talking about a pendulum?
Why is the motion of a pendulum simple
harmonic only at small angles?
For a pendulum in motion:
Where is the force greatest?
Where is the acceleration greatest?
Where is the velocity greatest?
Use figure 12-7 (p.444) to mathematically
explain the relationship between Mechanical Energy, Kinetic Energy, and
Potential Energy in a pendulum. (In other words, write an equation
that sums it all up.)
Why does an acrobat swing past the equilibrium
position when there is no force acting on her at that point?
