Which of the following best represents potential energy being converted to kinetic energy? a. a man jogs and stops to drink an energy drink. b. a drawn bow is released, causing an arrow to fly across a field. c. a roller coaster rounds a curve and climbs the next hill. d. a tree is struck by lightning, and then it is set on fire.

Answer;

B.  A drawn bow is released, causing an arrow to fly across the field.

Explanation;

Potential energy is the energy in a body due to its position. While kinetic energy is the energy in a body due to its motion. The formula for potential energy is mgh, where m stands for mass, g stands for gravitational acceleration and h stands for height.

Potential energy is the stored energy that can become kinetic energy. Kinetic energy is given by 1/2mv², where m is the mass and v is the velocity.

Potential energy = Stored energy, usually energy in bonds, energy in height.  

Kinetic energy = Energy of movement

As you draw the bow, the elasticity of the bow stores the energy (potential), and once you release, the arrow flies across the field (kinetic).
