Covered in AA SL, AA HL and AI HL, kinematics applies calculus to the motion of a particle. Students work with displacement s, velocity v and acceleration a as related functions of time, differentiating to move from displacement to velocity to acceleration and integrating to reverse the process. Total distance travelled is distinguished from net displacement using the integral of |v(t)|. In AI HL, kinematics also connects to the vectors subtopic through position vectors and variable velocity in two dimensions, including projectile and circular motion as special cases.
