Tutoring physics, you get asked about impulse now and again. The tutor introduces the topic, explaining its connection with momentum. Impulse has many definitions. Fundamentally, it means change in momentum. Momentum is a vector quantity, which means it has a …
Tutoring physics 12, you encounter this concept. The tutor offers the formula with an explanation. Induction refers to the creation of voltage in a wire that is not connected to a power source. It’s the premise that enables generation of …
Tutoring physics or chemistry, solutions to problems are often given in scientific notation. The tutor asks, “Is your calculator set conveniently?” Let’s imagine you have a physics problem whose solution is given by the following calculation: v = √(1.55×10-9) Of …

As a math tutor, you’ll likely introduce this concept. It’s used even more in physics and chemistry. So often in my university science courses I’d read “the mass is directly proportional to the volume” or “the distance is directly proportional …
Entering scientific notation on calculators is an important consideration. When you tutor high school sciences, you’ll want to mention it. If you’re a new arrival, you might want to read my previous post on scientific notation. Assuming you’re good with …
