The type of energy that depends on position is called
anyanavicka [17]
I think the correct answer is potential energy since an object at rest store energy as a result of its position and is called us such. For instance, a book placed in a table is storing energy as it held at an elevated position.

Claire is investigating potential and kinetic energy using a large ball. For her investigation, Claire will stand at the top of
uranmaximum [27]

The ball's potential energy will decrease, and its kinetic energy will increase.

Explanation:

The ball's potential energy will decrease down the slope and its kinetic energy will increase.

Kinetic energy is the energy due to the motion of a body.

 K. E = \frac{1}{2} m v²

 m is the mass of the ball

  v is the velocity of the ball.

Potential energy is the energy due to the motion of a body down slope.

It is expressed as:

   P.E = mgh

  m is the mass of ball

   g is the acceleration due to gravity of the body

  h is the height.

We can see as the body drops down the slope, the height diminishes and the velocity increases.
