Determining how fast something will be traveling upon impact when it is released from a given height.
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.
Plotting projectile displacement, acceleration, and velocity as a function of time.
Visualising position, velocity and acceleration in two-dimensions for projectile motion.
