AP Physics 1 FRQ Review - Mathematical Routines and Rotational Motion

Flashcards covering key concepts from a lecture on AP Physics 1, focusing on mathematical routines, free body diagrams, torque, forces, and rotational motion.

Mathematical Routines FRQ

Mathematical routines FRQ, involving derivation analysis and application of physics principles.

Forces Acting on a Disc Rolling Down a Ramp

The ramp exerts a normal force perpendicular to the surface and a static friction force directed upwards along the ramp.

Net Torque on a Disc Around Its Center

Net torque equals the force of friction times the radius (r).

Net Force Exerted on the Disc

Equals mg * sin(theta) - Force of friction.

Translational Acceleration of the Center of Mass of the Disc

(2/3) * g * sin(theta)

Experiment 2: Block of Ice vs. Disc

The block will reach the bottom faster because there is no friction. The net force down the ramp is greater, resulting in a larger acceleration.

Rolling without slipping

Implies static friction, as the disc rolls without rubbing against the surface.
