If the ball didn't make it to the end of the journey, then it presumably ran out of kinetic energy, said energy, energy of movement, either being converted to potential energy, or to heat energy as the case may be.
Conservation of energy means that the total, often the kinetic plus the potential, is constant. One decreases and the other increases, and vice versa, so that they all add up to the same amount.
ball released from rest at top of a track will have zero initial velocity. ball at the top of the track will have a potential energy of mgh. ball's vertical height above bottom of track gives the potential energy.

Explanation:
Answer:
Applied force
Explanation:
She is having to purposefully move the box herself to get it to go anywhere.
Answer:
Increasing the launch height increases the downward distance, giving the horizontal component of the velocity greater time to act upon the projectile and hence increasing the range.
Explanation:
Answer:
The Sun
Explanation:
It is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
