Topic 1
Kinematics
A rocket lifts off. Every second, its engine burns harder, so its acceleration keeps growing. Now try to find its speed with the equations from your first…

Topic 2
Force and Translational Dynamics
A cart runs around a vertical loop. At the very top it is completely upside down, with nothing holding it up. Why does it not fall off? The answer is not some…

Topic 3
Work, Energy, and Power
A block slides into a spring and squashes it until it stops. How far does the spring compress? Try that with a kinematic equation. You cannot — the force grows…

Topic 4
Linear Momentum
A car stops in a crash. With an airbag, the driver walks away. Without one, they do not. In both cases the momentum change is exactly the same — from full…

Topic 5
Torque and Rotational Dynamics
Push a door at the handle and it swings open easily. Now push just as hard, right next to the hinge. Almost nothing happens. The force was the same both times.…

Topic 6
Energy and Momentum of Rotating Systems
Watch a figure skater spin. Arms stretched out, she turns slowly. She pulls her arms in — and without pushing off anything, she spins much faster. Nobody…

Topic 7
Oscillations
In a science museum, a brass ball hangs from a very long wire. It swings all day above a marked floor, untouched. Every swing takes the same time as the last.…
