Kinematics
Terms, formulas, and an interactive lab: change the quantities and watch the graphs rebuild.
Basic concepts
Mechanical motion, reference frame, trajectory, distance and displacement, relativity of motion.
Uniform motion
Speed, average speed, coordinate versus time, graphs of velocity, displacement, distance and coordinate.
Uniformly accelerated motion
Acceleration, velocity and displacement at constant acceleration, speeding up and braking, graphs.
Free fall
Vertical motion under gravity: dropping, throwing up and down, graphs of acceleration, velocity and coordinate.
Motion in a circle
Curvilinear motion, uniform motion in a circle: period, frequency, linear and angular velocity, centripetal acceleration.
