An apple drops from the tree and falls freely. The apple is originally at rest a height 3 m above the top of the grass of a thick lawn, which is made of blades of grass of height 0.5 m. When the apple enters the grass, it slows down at a constant rate so that its speed is 0 m/s when it reaches ground level.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
