The energy being used to push a heavy box across the floor is mechanical energy. The person pushing the box is converting their own muscular energy into kinetic energy to move the box.
The kinetic energy of the ball in motion allows it to roll across the floor. As the ball is pushed or dropped, this kinetic energy is transferred to the ball's rotational motion, causing it to roll forward. Friction between the ball and the floor also plays a role in its movement.
Mechanical energy is being used when a person pushes heavy boxes across the floor. The person's muscles convert chemical energy into mechanical energy to move the boxes.
The energy being used is mechanical energy. When the person pushes the boxes, they are converting the chemical energy stored in their muscles into kinetic energy to move the boxes.
The kinetic energy of the toy marble as it moves is what allows it to roll across the floor. This energy comes from the marble's motion and speed.

The force diagram for a crate being pushed across the floor would typically show a horizontal force in the direction of the push, a normal force (perpendicular to the surface), and a frictional force opposing the motion. The sum of these forces determines the crate's acceleration or equilibrium.
