Final answer:
The type of energy transfer is mechanical energy transfer when a ball rolls down a ramp into another object causing it to move.
Step-by-step explanation:
The type of energy transfer when a ball rolls down a ramp into another object causing it to move is mechanical energy transfer.
When the ball rolls down the ramp, its potential energy (due to its position at the top of the ramp) is converted into kinetic energy (due to its motion). As the ball collides with the other object, this kinetic energy is transferred to the object, causing it to move. This transfer of energy is an example of mechanical energy transfer.
