AP physics unit 5 equations that are importance (mainly for inertia equations)

I = m * r²

Moment of Inertia (Point Mass)

I = (1/2) * m * r²

Moment of Inertia (Solid Disk or Cylinder about Central Axis)

I = m * r²

Moment of Inertia (Thin Hoop about Central Axis)

I = (2/5) * m * r²

Moment of Inertia (Solid Sphere about Central Axis)

I = (2/3) * m * r²

Moment of Inertia (Hollow Sphere about Central Axis)

I = I_cm + m * d²

Parallel Axis Theorem

sum τ = I * α

Torque Equation (Rotational Newton's 2nd Law)

KE_rot = (1/2) * I * ω²

Rotational Kinetic Energy

τ = r × F

Torque
