Question

1. at this skater position what is the skater energy? and why?

a. potential:

b. kinetic:

Explanation:

For potential energy: The skater is at a certain height (on a peak in the track). Gravitational potential energy depends on height ($PE = mgh$), so at this position, potential energy is relatively high (compared to lower points) because height $h$ is significant. For kinetic energy: Kinetic energy depends on speed ($KE=\frac{1}{2}mv^2$). At this peak, the skater’s speed is likely low (maybe momentarily at rest or slow), so kinetic energy is low.

Answer:

a. Potential: Relatively high (or significant). Because the skater is at a certain height (on the peak of the track), and gravitational potential energy ($PE = mgh$) depends on height, so with a non - negligible height, potential energy is high.
b. Kinetic: Relatively low (or small). Because kinetic energy ($KE=\frac{1}{2}mv^2$) depends on speed, and at this peak position, the skater's speed is low (possibly near - rest or slow - moving), so kinetic energy is low.
