If you multiply velocity by time, you will get the distance (assuming constant acceleration), but if the car moved at 10 km per hour for 5 minutes, multiplying 10 by 5 will not give you the right answer.Rather, you will need to either convert the kilometers per hour to kilometers per minute, or (and probably easier) convert 5 minutes to units of hours.
However, the more you use the formulas, and the more you understand what they mean and – if you care enough to check – where they came from, the easier it gets to remember them. If you have a cheat sheet, align it next to your variables. In fact, in the vast majority of questions, no matter what equation you use – assuming that it is relevant to the subject matter, and that you insert the proper variables – you will reach a solution.
What formula can you fill up, leaving the least amount of missing variables? The way to know which equation to use depends on two main issues: the variables given to you in the equation and your experience.
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.
I remember taking an advanced electromagnetism course where I had to memorize about 20 different formulas. They are derived from physical properties, and they are all interconnected.

At first it seemed terrible, and I kept remembering them wrong. You look at your formula sheet and you have three different ones that are marked under the problem’s subject. In most physics problems, there is more than one way to reach a solution, often meaning that more than one equation can work.For example, getting a visual idea of your frame of reference, or of the difference between up (positive) and down (negative), can mean the difference between a right answer and a wrong one. Go on, Picasso, give it your best shot, and move on to the next step.Sometimes your professor will test your unit conversion skills.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.This begins with very basic physics, but continues with higher level material.The difference seems to be that only those who like physics – and find a good way of dealing with it – stick around to deal with the higher level stuff. You don’t have to understand all the small details, but once you know what you’re dealing with in general, you will know how to formulate your answer and which equations to use.Most of them shy away from physics problems, though, letting me – and a handful of other tutors – deal with the dreaded subject.In general, physics seems to have this aura to it that scares people before they even start solving a problem.Other times, there will be variables whose purpose is revealed in a later part of the question.For example, if the question has a car that starts to move from rest and takes 5 minutes to reach a speed of 20 km/h, you should write down the basic variables like so: Do this with all the information you get out of the question.
