Physics Homework Helpers

Having tutored middle school, high school, and college sciences, there’s no limit to the number of topics that confuse students- especially when it comes to math and logic related exercises in physics and chemistry.

I programmed these physics homework helpers back in 2011, but in 2013 retouched them to work within a responsive website.  You should be able to use them on a phone, tablet, or computer.

Below are the currently available online physics homework helpers:

Calculate the force of gravity on the 1-kg

mass if it were 3.2×106m

above Earth’s surface (that is, if it were one and a half Earth radii from Earth’s center). How do I solve this

That’s a Universal Law of Gravity problem. You should be using Fg = G (m1 * m2) / r^2 ; where G = universal gravitation constant, m1 = 1 kg, m2 = mass of earth, r = radius of Earth + 3.2×10^6 m
