Physics: Understanding Our Interactions

From an early age, children begin to grasp the principles of physics, even if they don’t recognize it. For instance, a toddler may not comprehend the concept of force when lifting a toy, yet they are instinctively applying it. Similarly, when they kick a ball, they are using a pushing force without being aware of it. As they grow, whether through sports or music, they continue to experiment with concepts such as momentum, power, pressure, work, and kinetic energy, all of which are foundational elements in physics.

In essence, physics permeates every aspect of our lives. Some might argue that it is only relevant for those seeking white-collar jobs or higher education. While I understand this perspective, I contend that studying physics equips individuals with a wealth of knowledge that can be invaluable in various situations—essentially offering alternative explanations when needed.

One compelling illustration of the application of physics is in weightlifting.

When engaging in weightlifting, individuals repeatedly lift and lower heavy weights in a controlled manner. If we analyze this activity from a physics standpoint, several variables come into play, such as:

• “W”: The weight being lifted
• “S”: The strength of the muscles, which can vary over time
• “M”: The movement of the weight, which can also be viewed as a function of time, with the weight's position as the dependent variable.

In my experience with weightlifting, understanding the application of force is pivotal. For instance, during a bench press, the barbell exerts a downward force, and the lifter must generate a greater upward force through their pectoral muscles to lift it. This basic principle becomes more intricate when considering static positions, such as wall sits.

Initially, one might start with their feet on the ground, but as fatigue sets in, maintaining this position can become challenging. In such cases, having a heavy object to push against can be beneficial. Why? Because heavier objects create a greater coefficient of static friction, making it easier to stabilize oneself.

Section 1.1: Physics and Sensory Interaction

Beyond understanding our physical interactions, physics also offers insights into how the world affects us. The human brain, often dubbed the greatest supercomputer, processes sensory information and generates thoughts based on what we see, hear, smell, touch, and taste. Movement alone can stimulate mental activity, which is why resting can feel refreshing.

However, stress can lead us to seek solace through practices like meditation.

While I’m not an expert in neuroscience, I can observe the basic components of meditation: sitting still, closing one’s eyes, and relaxing the body in a tranquil environment. This state of being can be defined as a withdrawal from reality, or “NOT R.”

Where Does Physics Fit In?

Consider a scenario where one might feel stressed but cannot close their eyes due to responsibilities. In this instance, they can engage in a form of pseudo-meditation—staying still and minimizing movement. Though this may not be as effective as traditional meditation, extending this practice can still yield benefits.

This might seem trivial, but it illustrates how principles from physics (and math) can be applied to tackle everyday challenges.
