General Physics & Physics for engineering

Welcome to Kinematics—the study of how things move!

We are zooming in on one-dimensional motion (moving strictly back and forth or up and down in a straight line). For now, we don't care why things move, what forces are pushing them, or what engine is powering them. We are strictly focusing on the pure magic of the movement itself.

Before we can map out our journey, we need to master three fundamental superpowers:

• Displacement: Where are you now compared to where you started?
• Velocity: How fast are you going, and in what direction?
• Acceleration: How quickly are you changing your speed or shifting gears?
