The previous lecture was long and demanding, both conceptually and mathematically. Which I intentionally did not mean to make this long, however I thought it would be a better idea to discuss mathematical reasoning and the ideas behind them. We … Continue reading →

Among all the forces we encounter in everyday life, gravity is the most familiar and at the same time the most easily overlooked. It acts on every object around us, from falling stones to the air we breathe, and it … Continue reading →

In the previous lecture, we arrived at a compact statement that connects force, mass, and acceleration. Written as $F = ma$, it summarizes a long chain of reasoning rather than replacing it. Forces are responsible for changes in motion, mass … Continue reading →

In the previous lecture, motion was described using position, velocity, and acceleration. Among these, acceleration stood out as something special. Acceleration appears whenever motion changes, whether an object speeds up, slows down, or changes direction. Physics treats this change in … Continue reading →

In everyday language, motion seems like one of the simplest ideas there is. If something changes its place, we say it is moving. A car travels along a road, a bird flies through the air, the hands of a clock … Continue reading →

Some people think of physics as a set of problems, laws, and formulas to solve. That way of thinking is wrong. Physics is really just trying to figure out how nature works by using ideas that are as simple as … Continue reading →
