In this tutorial, you will learn about how forces interact to produce projectile motion of a cannonball as it is launched from a catapult. You will begin by opening the Unity editor and downloading the project assets by following the included link. When you have the assets loaded and configured, you will start lesson one and begin working through the included steps. By changing the sliders that control your cannonball’s mass and the spring force of your catapult, you will watch how the forces applied by a catapult affect the arc and speed of a projectile. Using the data set you collect from the launch; you will calculate the acceleration of your cannonball. Once you are finished with the lesson activity, you will move on to the target free play section and experiment with mass and force until you are able to hit the center of a target.
You will be able to explain the relationship between the forces applied to a cannonball, the mass of the ball, and the ball’s acceleration. Using what you've learned, you will find the optimal mass and force settings needed to hit the bullseye on a target.
By the end of this lesson, you will be able to:
