Answer:
Tbh i rlly dont think that many will. Most may succeed in doing so. But i mean come on its 2020 anything can happen.

Answer:
what is ionic? Is it iron
Explanation:
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.

Answer:
D. The bike experiences a contact force and Earth experiences a non-contact force.
All moving objects have kinetic energy.
Kinetic energy is the energy of motion, therefore if an object is moving it has kinetic energy.
