Which of these is exhibiting kinetic energy? A. An archer with a flexed bow B. A person sitting on a couch while watching TV C. A space station orbiting Earth D. All of the above

An archer with a flexed bow
A person sitting on a couch while watching TV
A space station orbiting Earth
All of the above

The correct answer is D. All of the above.

Kinetic energy is the energy of motion. It is possessed by an object due to its motion. The more mass an object has, the more kinetic energy it will have if it is moving at the same speed. The faster an object is moving, the more kinetic energy it will have.

An archer with a flexed bow has kinetic energy because the bow is moving. The bow is moving because the archer has pulled back the string, which has stored energy in the bow. When the archer releases the string, the energy in the bow is transferred to the arrow, which causes the arrow to fly.

A person sitting on a couch while watching TV does not have kinetic energy because the person is not moving. However, the person’s body does have potential energy because of its position above the ground. If the person were to fall off the couch, the potential energy would be converted into kinetic energy as the person fell.

A space station orbiting Earth has kinetic energy because it is moving. The space station is moving because it was launched into orbit by a rocket. The rocket’s engines provided the space station with the initial kinetic energy it needed to orbit Earth. The space station’s kinetic energy keeps it from falling back to Earth.

In conclusion, all of the options in the question exhibit kinetic energy.
