Question

practice it!
which of the following identifies the positions
with high potential energy and no kinetic energy?
a
e
d
b
c

Explanation:

Potential energy is related to height (\(PE = mgh\), where \(m\) is mass, \(g\) is acceleration due to gravity, and \(h\) is height). Kinetic energy is related to motion (\(KE=\frac{1}{2}mv^{2}\), where \(v\) is velocity). At the highest point of a pendulum - like motion (assuming this is a pendulum - related setup), the object has maximum height (so high potential energy) and at the extreme positions (A and E), the velocity \(v = 0\) (so no kinetic energy).

Answer:

A. Option A, E. Option E
