The skater is at the bottom of the pipe. What energy is it

At the bottom of a half-pipe, a skater primarily possesses kinetic energy due to their speed. If we consider the skater's position at the bottom of the pipe, two forms of energy are relevant:
1. **Kinetic Energy (KE)**: This is the energy the skater has due to their motion. It can be calculated using the formula:
\[
KE = \frac{1}{2}mv^2
\]
where \( m \) is the mass of the skater and \( v \) is their velocity at the bottom of the pipe.
2. **Potential Energy (PE)**: When the skater is at the bottom of the pipe, their gravitational potential energy is at its minimum (typically defined as zero at this point). If the skater started from a height in the pipe, they would have gained kinetic energy as they descended.
So, at the bottom of the pipe, the skater has maximum kinetic energy and minimum (or zero) potential energy. If we were considering the overall energy of the system, conservation of energy principles would apply, meaning that the total mechanical energy (kinetic plus potential) would remain constant, assuming no energy is lost to friction or air resistance.
