Happy first day of school! This semester, I'm teaching:

1. #PHY131 Quantum Physics and Technology for Everyone #QuantumForEveryone, a new 2-credit general education course
2. #PHY201 General Physics for the Life Sciences 1 #GenPhys1
3. #PHY531 #QuantumMechanics
Today in #PHY201 #GenPhys1: SI units are the same across the universe. Prefixes multiply units by powers of 10. Dimensional analysis helps rule out incorrect equations. Distance--a scalar--is the length of path traveled. Displacement--a vector--is change in position.

Today in #PHY201 #GenPhys1: Velocity is change in position (Δx) over change in time (Δt). On a position vs time graph, Δx is the rise, and Δt is the run, so velocity is the slope. With constant velocity, v = v₀ and x = v₀ t + x₀.

Today in #PHY201 #GenPhys1: Assuming constant acceleration, we derived four kinematic equations involving different variables. They also apply to free fall motion, where acceleration due to gravity near the surface of the earth is approximately constant. pic.twitter.com/uBFrKaQFDf

Today in #PHY201: For the motion of a projectile, there is constant velocity in the x-direction and constant acceleration (due to gravity) in the y-direction, resulting in six kinematic equations describing the motion. pic.twitter.com/yOmI9C4AzI
