Mass on a spring
To slow down the motion, set the spring constant to a small value.
The mass of the block is 1.0 kg.
The positive direction is to the right. The equilibrium position
is indicated by the thin blue rectangle.
Things to think about:
- Does the law of conservation of energy apply here?
- How does the initial displacement from the equilibrium
position affect the total energy? How does it affect the maximum
speed of the block?
- Where does the block reach its maximum speed? In what form is
the energy (how much potential and how much kinetic) at this point?
- Is there any connection between the direction of the displacement
and the direction of the acceleration (the acceleration indicates the
direction of the force applied by the spring on the block)?
- Is the frequency of the motion affected by the initial
displacement? How does it depend on the spring constant?
