Motion in Two Dimensions

In this chapter, we’ll use vectors to expand our understanding of forces and motion into two dimensions. Most real-world physics problems (such as with the game of pool pictured here) are, after all, either two- or three-dimensional problems and physics is most useful when applied to real physical scenarios. We start by learning the practical skills of graphically adding and subtracting vectors (by using drawings) and analytically (with math). Once we’re able to work with two-dimensional vectors, we apply these skills to problems of projectile motion, inclined planes, and harmonic motion.

Projectile Motion

  • Determine how each parameter (initial height, initial angle, initial speed, mass, diameter, and altitude) affects the trajectory of an object, with and without air resistance.
  • Predict how varying the initial conditions will affect a projectile’s path, and provide an explanation for the prediction.
  • Estimate where an object will land, given its initial conditions.
  • Determine that the x and y motion of a projectile are independent.
  • Investigate the variables that affect the drag force.
  • Describe the the effect that the drag force has on the velocity and acceleration.
  • Discuss projectile motion using common vocabulary (such as: launch angle, initial speed, initial height, range, time).
