We can confirm that in a roller coaster, kinetic and potential energy in the car decreases at each successive hill because of the force of gravity which converts potential energy into kinetic energy.
<h3>What are potential and kinetic energy?</h3>
Potential energy is referred to as <em><u>positional energy</u></em>.
This means that the object in question gains energy based on its position relative to others.
Kinetic energy is the energy of movement.
Gravity causes the roller coaster to fall, losing potential energy.
This causes it to gain all of the potential energy as kinetic energy.
Once at the bottom, the coaster no longer moves and thus loses the kinetic energy as well.
Therefore, we can confirm that gravity is the force that causes the shift from potential energy to kinetic energy and thus causes them both to decrease after each successful hill in the roller coaster.
The forward reaction is favoured in order to reduce the disruption (excess heat) to the system. Position of equilibrium shifts rightwards of the equation for excess heat to be absorbed during the endothermic forward reaction
