Perhaps you’ve seen videos of how the planets of the solar system move through the universe in this cool helix. Not only are these misleading, but the Earth’s real motion - YOUR motion through the universe, is way more complicated and...

CALCULUS! Today we take our first steps into the language of Physics; mathematics. Every branch of science has its own way to describe the things that it investigates. And, with Physics, that's math. In this episode, Shini talks us...

When you hear the word, "Work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in Physics and today, Shini is going to...

In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also,...

We have learned over the past few weeks that gases have real-life constraints on how they move here in the non-ideal world. As with most things in chemistry (and also in life) how a gas moves is more complex than it at first...

Mr. Andersen explains the basic quantities of motion. Demonstration videos and practice problems are also included. The difference between scalar and vector quantities is also discussed.

In this video Paul Andersen explains how the macroscopic measure of temperature can be related to the average kinetic energy of molecules in motion. The Boltzmann constant and distribution can be used to calculate the root mean square...

Struggling with forces and Newton’s Laws in AP® Physics 1? In this lesson, we clear up some of the most common stumbling blocks from roughly the first half of Unit 2, including center of mass, translational equilibrium, constant velocity...

Master the fundamentals of AP Physics 1 Unit 1: Kinematics with this clear, example-driven walkthrough of common stumbling blocks students face. We’ll break down how instantaneous velocity differs from average velocity, why “negative...

Master the fundamentals of motion in a straight line with this summary of 7 key kinematics lessons. Includes solved problems, essential tips, and downloadable PDFs—ideal for JEE, NEET, and AP Physics students seeking conceptual clarity...

This content provides a conceptual understanding of average velocity for a particle moving along a semicircular path. It emphasizes that average velocity is calculated based on displacement (the straight-line distance between start and...

This content provides a detailed example of vector motion, analyzing a plane's journey in two segments. It demonstrates how to calculate the total displacement (magnitude and direction) using vector notation, determine the average...

Learn the key differences between average velocity and average speed, and why they matter in analyzing motion. We’ll use simple motion scenarios and velocity-time graphs to explore how direction affects velocity, but not speed.

In this video, we go over practice problems related to speed and velocity. This video is a follow up video to our concept video on Speed vs. Velocity. Students will learn 1 easy way to solve any speed or velocity problem and perform the...

The speed of an object in a particular direction.

This review of Unit 1: Kinematics for AP Physics 1, we cover essential topics such as significant figures, conversions, vectors and scalars, and key kinematic equations. It emphasizes the importance of understanding vector quantities...

In this episode of Flipping Physics, we delve into the intriguing world of magnetic forces in current-carrying wires. Ever wondered how the net magnetic force on a wire is calculated when charges are on the move in a wire? We break down...

We explore the concept of electric current and conventional current, which is the direction that positive charges flow, and the reality that electrons move in the opposite direction in most circuits. We derive the equation for average...

The derivative is introduced and several examples are worked through. The difference between average and instantaneous velocity is demonstrated on a graph. The derivative of a power function rule is worked through. Again, graphs are used...
