That isn’t without a purpose – in physics (and science in general), units are crucial.
If you organize your information, your brain will be free to deal with actual physics instead of reading comprehension. Some questions already come with a drawing – use it!
In physics, drawing a picture can really make things easier. Arrows are your friends in physics questions – they show you which direction an object is moving or what the possible sum of forces applied to it are. Questions about forces, for example, are best solved by schematic, and you can miss some crucial information that you don’t immediately see if you don’t sketch it.
Some professors will require that you memorize relevant formulas, while others will give you a “cheat sheet.” Either way, you have what you need.
Memorization might sound horrible, but most physics subjects don’t have that many equations to memorize. Physical equations didn’t just land on scientists from the sky, all wrapped up nicely in mathematical formulation.
What you are expected to do is to understand the concepts and use the tools available to you.
The most important of those tools are the formulas.Read the question carefully – this isn’t the time to skim. Word problems are confusing only because they hide the actual variables inside them.Sometimes, you will be given extra information that you won’t really need.This semester I started tutoring in the physics and math study center.I am the only “pure” physics tutor – the rest of the tutors are mathematicians or engineers who feel very comfortable with mathematics (justly so, they’re all quite awesome).This is true for most of physics questions, and absolutely true in the lower level physics.As a student of basic physics, you are not expected to reinvent the wheel – or even understand how the wheel was invented in the first place.If we continue our example from the last part, we should convert the t(final) from minutes to hours.This isn’t too hard to do: \(5 \text * \frac = \frac \text\) Now that all your variables are in the correct units, you can continue solving the question.The best way to do this is by fractions, but there are enough unit conversion guides out there that explain this concept.Remember not to panic, do it carefully and you will get your correct values.
