Kinematics
Build the language and mathematical models used to describe position, displacement, velocity, acceleration, uniformly accelerated motion, and free fall.
Open the unit- Scalars, Vectors, Distance, and DisplacementDistinguish scalar quantities from vectors, then compare the path traveled with the change in position from start to finish.
- Speed, Velocity, Average, and Instantaneous MotionDistinguish speed from velocity, compare average and instantaneous values, and use a one-lap track example to see why average speed can be nonzero while average velocity is zero.
- Acceleration: Changing Velocity and DirectionDistinguish acceleration from velocity, interpret positive and negative directions, and decide whether an object speeds up, slows down, stops, or reverses.
- Uniform Accelerated Motion (UAM) EquationsLearn when the constant-acceleration equations apply, how they are built from familiar rate equations, and how to choose the equation that matches the knowns and target.
- Uniform Accelerated Motion (UAM) ExamplesWork through seven constant-acceleration examples using a consistent read, list, select, rearrange, substitute, solve, and check process, with careful attention to signs, units, and the meaning of each result.
- Free FallPredict free-fall motion using the gravity-only model, explain why mass does not change ideal free-fall acceleration, assign the sign of g, and distinguish velocity from acceleration during an upward toss.
- Free Fall Example ProblemsWork through seven free-fall problems in teaching order using hidden knowns, consistent sign conventions, equation selection, units, and physical checks—including a careful distinction between ascent time and total airtime.
- Isolating Variables: A Physics Math ReviewRearrange physics equations symbolically by preserving equality, undoing operations in a useful order, respecting grouped terms, factoring repeated targets, and recognizing equivalent final forms.
