The ABC’s of PhysicsBefore we dive into forces, gravitational or otherwise, we should understand the underlying concepts of motion in a framework of space and time. We need a foundation on which...

We’ve always wondered whether it’s possible to calculate the position of a dropped or thrown object. While we could certainly investigate this matter by rigorous experimentation, we don’t hav...

Now that’s we’ve mastered motion and vectors to at least a moderate degree, we’re prepared to study forces, another vector quantity related to motion. And how could we possibly study forces w...

The force of gravity, famous for allegedly dropping an apple on Sir Isaac Newton’s head and thereby furthering the development of physics, is still perhaps the least understood of standard non-co...

As we learned in the introduction to Newton’s Second Law and witnessed with orbital motion and the Universal Gravitation Law, an unbalanced force leads to acceleration. And, as we saw in projecti...

Introduction to MotionReview the whole scalar/vector business with every sunrise until the whole positive vs. negative acceleration thing makes sense. Also: notation, notation, notation. A vector s...

Introduction to Motion1. What type of motion is ? Detail as much as possible.2. What is the total displacement for the sum of ?3. A bicycle decreases speed from to rest in 5 seconds. What’s its...
