Skating can be more fun especially when you know how to execute some cool moves without requiring too much effort. This is why we’ll dive deeper into the basics of energy skate park to know the hidden science behind it, and in order to perform better at skating. Hopefully, this feature which contains its four basic concepts will not only be educational, but instructional as well.
First Concept: Kinetic Energy
An energy of motion is basically kinetic energy. For example, a skater that has horizontal motion along the U-ramp, has some amount of kinetic energy. Additionally, it is a scalar quantity that can be fully described by numerical values alone. The object will maintain its level of kinetic energy as long as its speed will remain unchanged, or given that there’s an absence of friction. However, the same amount of work needed to accelerate the object should be applied if you want to decelerate the object back to rest.
Second Concept: Potential Energy
It basically means some stored energy that depends on the relative position of the particular object. For example, the higher the skater is resting on top of the U-ramp, the more potential energy it has. In other words, the skater in a raised position is capable of doing more work.
Furthermore, potential energy is dependent on the initial and final configurations. Let’s say if the initial position of the skater is on ground level and his final position is 25 m above the ground, the potential energy remains the same no matter how high he’s at. Therefore, the value of potential energy is relative to the chosen reference point.
Third Concept: Conservation of Energy
Before understanding this scientific principle, you must first know that energy can neither be created nor destroyed. It is the law of science which tells us that the energy of objects in a closed system remains fixed. Although it can be converted from one form to another, you can’t create additional energy inside the given system nor destroy the current energy present inside there
The “closed systems” can be represented by a closed box around a particular thing we’re studying. No energy can leak from the box (or be absorbed by the box from the outside).
Fourth Concept: Thermal Energy
It refers to the energy within the system that is responsible for producing temperature. A branch of physics is dedicated in studying how heat is the flow of thermal energy. For example, a skater in a constant velocity along the U-ramp.
Since friction is none conservative, the work done by the skates isn’t stored as potential energy. Consequently, all the work done by friction is converted as thermal energy in the skate-ramp system. Furthermore, thermal energy flows within the wheels and the ramp, thus raising the temperature of both objects.
Understanding the science behind energy skate park is essential for every skate learner out there. It can be used as a basis in order to have better endurance and perform with finesse.
