Answer

Brief Explanations:

When the toy jumps into the air in Step 4, the compressed - spring (which had elastic potential energy) expands and the toy gains height. Elastic potential energy stored in the spring is converted into gravitational potential energy as the toy moves upwards against gravity.

Answer:

Elastic potential energy changes to gravitational potential energy.
