The spring constant of an object tells you?

• What type of spring you are dealing with

• How long the spring will stretch or compress

• It gives you a value on how easy or hard it is to change the objects length.

• A spring constant gives you a number which tells you what material the spring is made of.

A mass attached to a spring vibrates back and forth. At the equilibrium position, the

• acceleration reaches a maximum.

• velocity reaches a maximum.

• net force reaches a maximum.

• velocity reaches zero.

Which position shows the spring with maximum elastic potential energy?

• A

• B

• C

• D
