Sometimes it just picks for you
Answer:
Decreasing in altitude and increasing in velocity
Explanation:
The formula for potential energy is:

where m is mass, g is constant gravitational energy and h is the potential altitude.
The formula for kinetic energy is:

where v is the velocity
Since m,g are constant, to convert from potential energy to kinetic energy, h must decreases while v increases. For example dropping an object from a height.
ind the velocity my using the conservation of energy mgh=1/2mv^2. At the bottom, the mass is turning in a circle with tension pointing up towards the center of the circle and weight pointing down. Use the centripetal force requirement mv^2/r=T-W and solve for T. Hope this helps.
The kinetic energy decreases
They are a variable that changes as a result of the changes in the manipulated variable
