Uniform Circular Motion

• Overview
• Determining the period, T, of an object in circular motion
• Determining the velocity of an object using v = 2πr/T
• Determining the centripetal force acting on an object using F_c = (mv²) /r
• Determining the centripetal acceleration of an object using a = v²/r

Center of Mass

• Overview
• Determining the center of mass for objects positioned along the same straight line
• Determining the x- and y-coordinates of the center of mass for objects.

Torque

• Overview
• Calculating the magnitude of the torque of F using τ = rFsinθ or τ = rF_⊥
• Calculating the net torque on an object with multiple forces acting on it

Rotational Kinematics

• Overview
• Calculating the average angular velocity
• Calculating the average angular acceleration

Angular Momentum

• Overview
• Determining the angular momentum using the equation L = rmv_⊥
