Question

which of the following scenarios does not demonstrate a transfer between potential energy and kinetic energy?
a \tusing a playground slide
b \tgoing down stairs
c \tbouncing on a trampoline
d \tsitting still at in your school desk

Explanation:

• For option a: On a playground slide, a person starts with potential energy (due to height) and as they slide down, potential energy converts to kinetic energy (motion), so there is energy transfer.
• For option b: Going down stairs, a person's height decreases (potential energy decreases) and speed (kinetic energy) may increase, showing energy transfer between potential and kinetic.
• For option c: Bouncing on a trampoline, when you jump up, kinetic energy converts to potential energy (at the peak), and when you come down, potential energy converts to kinetic energy, so there is transfer.
• For option d: Sitting still at a school desk, there is no change in height (so potential energy is constant) and no motion (kinetic energy is zero or constant), so no transfer between potential and kinetic energy.

Answer:

d. sitting still at in your school desk
