question 10 of 27
the graph below shows the conservation of energy for a skydiver jumping out of a plane and landing safely on the ground. which energy is represented by line c?
energy (kj)
a
c
b
distance (m)
a. total energy
b. kinetic energy
c. mechanical energy
d. potential energy

Explanation:

In the case of a skydiver, total mechanical energy (sum of kinetic and potential energy) is conserved in the absence of non - conservative forces. As the skydiver falls, potential energy decreases and kinetic energy increases. Total energy remains constant throughout the fall. Line C is horizontal, indicating a constant value. Total energy remains constant during the skydiver's motion (neglecting air - resistance for the concept of energy conservation).

Answer:

A. Total energy
