Answer:
a space station orbiting Earth
Explanation:
Kinetic energy in an object arises from the motion of the object.
[tex]\frac {1}{2}\times m\times v^2[/tex] is the kinetic energy of object.
(a) a person sitting on a couch while watching TV
The person is still and is not in motion and thus, do not exhibit any kinetic energy.
(b) an archer with a flexed bow
The archer hold the bow flexed. It may have a lot of potential energy but not kinetic energy as it is still.
a space station orbiting Earth
The space station is moving and is in motion and thus, exhibits kinetic energy.
(c) a rock on a mountain ledge
The rock is on a mountain ledge . It may have a lot of potential energy but not kinetic energy as it is still.
(d) the high-energy phosphate bonds of a molecule of ATP
The bonds are still and is not in motion and thus, do not exhibit any kinetic energy.
