Why use energy bar charts?

Jacobs Physics

The usefulness of graphical representations over straight-up equations and calculations for understanding energy concepts has been well established in physics teaching literature for years. I resisted teaching energy bar charts for nearly the first two decades of my career - mainly for point (3) above.

Mail Time: Gravitational potential energy in orbits

Jacobs Physics

One of the Fundamentals Quiz questions in the leadup to the 2023 AP exams asked about gravitational potential energy in orbits: 118. Which has greater gravitational potential energy: the satellite A-earth system, or the satellite B-earth system? Physics is not my strong suit and I understand why using Ug = mgh.

AP Physics 1 and AP Physics C - Mechanics Daily Review: Fundamentals check 9

Jacobs Physics

These fundamentals checks are just as appropriate for AP Physics C (mechanics) as for AP Physics 1. because I'd teach it as just AP Physics 1 until about March. because I'd teach it as just AP Physics 1 until about March. What is the total kinetic energy of the two-cart system? That's totally doable.

Center of mass calculations for AP Physics 1

Jacobs Physics

The revisions to the AP Physics exams for 2025 are imminent. I've posted about the formatting changes , which are truly no big deal for physics 1/2, and are so, so welcome in physics C. The *content* changes are nonexistent in physics C. The *content* changes are nonexistent in physics C. But what else is there?

The Future of Physics: String Theory

STEMe

In Einstein's theory of gravity, you would need a boson called a graviton, but in the standard model, when accounting for a graviton mathematically there are infinities. In some particle-accelerator experiments, physicists realized that a hadron's angular momentum was exactly square to the proportion of its energy.
