What happened to the period of oscillation for this mass-spring system as the mass? Increased? Give a conceptual explanation (no equations) of why the period would do this. Think about how forces affect objects with larger masses.

As mass increases, the time period increases.

Explanation:

Let a block of mass m is attached to a spring of spring constant K is set into oscillations.

The time period of the oscillation is defined as the time taken by the system t complete one oscillation.

The formula for the time period of spring mass system is given by

where, m is the mass of the block and K is the spring constant.

If the mass of the block increases, the time period of the system also increases.
