potential and kinetic energy\nthe ball is rolling down the ramp. which statements are true about the…

Explanation:

Step1: Recall energy - formulas

Potential energy $U = mgh$ (where $m$ is mass, $g$ is gravitational acceleration, $h$ is height). Kinetic energy $K=\frac{1}{2}mv^{2}$ (where $v$ is velocity).

Step2: Analyze height - change

As the ball rolls down the ramp, its height $h$ decreases. Since $U = mgh$ and $m$ and $g$ are constant, the potential energy $U$ decreases.

Step3: Analyze velocity - change

As the ball rolls down the ramp, its velocity $v$ increases. Since $K=\frac{1}{2}mv^{2}$ and $m$ is constant, the kinetic energy $K$ increases.

Answer:

The potential energy is decreasing. The kinetic energy is increasing.
