Answer

Explanation:

Step1: Recall energy - conservation formula

Total energy (E = K + U), where (E) is total energy, (K) is kinetic energy and (U) is potential energy.

Step2: Solve for potential energy

Given (E = 20\ J) and (K=5\ J), we substitute into the formula (U=E - K). So (U = 20 - 5=15\ J).

Step3: Analyze energy - change relationship

According to the law of conservation of mechanical energy (assuming no non - conservative forces), (E = K+U=\text{constant}). If (K) decreases, then (U) must increase to keep (E) constant.

Answer:

15; increase
