Essential Physics Formulas
Ever wonder why things weigh less on the moon? The relationship between mass and weight explains it all! Mass stays constant (measured in kg or g), while weight changes depending on gravitational field strength. On Earth, gravitational field strength is 10 N, but only 1.6 N on the Moon and a whopping 25 N on Jupiter.
Understanding motion requires three key relationships. Speed tells you how distance and time relate Distance=Speed×Time. When speed changes, we're dealing with acceleration, which connects velocity changes with time Acceleration=Changeinvelocity÷Time. Remember that velocity is measured in m/s while acceleration is m/s².
Pro Tip: When solving physics problems, always write down what you know and what you're looking for before plugging numbers into formulas. This makes complex problems much easier to solve!
These formulas aren't just abstract math—they explain everything from why you feel "weightless" on roller coasters to how fast you need to drive to reach school on time. Mastering these basics will make more advanced physics concepts click into place.
