Challenge Overview: Use the skills you’ve learned in the previous two lessons to score on a basketball hoop. After you’ve scored, you will have to use the hierarchy and inspector windows to manipulate the way your catapult works. When you’ve found out how to make changes to your catapult, try the Free Play activities again using different catapult settings. When you’ve finished working with the catapult settings, look at the code that calculates the values you see inside the simulation. Challenge Outcome: Catapult will throw a cannonball through a basketball hoop Catapult settings and characteristics will be manipulated Editor code will be investigated Challenge Objectives: In this challenge, you will reinforce the following skills/concepts: Using mass and force sliders to send a cannonball to a specific location Use the hierarchy menu to select elements of your catapult Adjust the launch settings of your catapult using the inspector window in Unity Complete the Free Play activities without the use of the force and mass sliders Adjust the project settings and investigate the effect of your changes in the Free Play activities Look at the code that allows the physics editor to make calculations

In this tutorial, you will learn how to use the Physics Debugger.

Previously, Unity had one physics Scene that was populated with all the bodies and colliders from all of your Unity Scenes. Starting in Unity 2018 LTS, you can split physics across Scenes. In this tutorial, you'll learn the basics of creating and loading alternate physics Scenes that can overlay a main scene.

The PhysX 3.4 upgrade in Unity 2018 LTS allows you to create multiple physics Scenes. In this project, you'll learn the basics of Multi-Scene Physics to create a "ghost" ship in the Hover Racer game.

For assets in a 2D project to have a physical presence in the Scene and be able to interact with each other, they must have a 2D Collider. A 2D Collider is a component that helps define an asset’s physical shape to determine how it will interact with other colliders in a Scene. In this tutorial, you'll learn about the types of 2D Colliders you can use, and you'll apply a Collider to a GameObject.

Physics enables objects to be controlled by (an approximation) of the forces which exist in the real world, such as gravity, velocity and acceleration. This tutorial will serve as an introduction to many of the key concepts

Overview: In this tutorial, you will learn about the relationship between mass, force, and energy as you calculate the velocity and acceleration of the cannonball on your worksheet. You will begin by opening lesson two and looking at how the mass and force sliders you used in the last lesson affect the energy involved in a catapult launching a projectile. When you’ve used your sliders to change the energy being used in your catapult, you will launch the ball and track the energy associated with the ball through its arc between the catapult and the ground. Using the law of conservation of energy, you will explain how energy is used and transferred by the catapult. Using one of the kinematic equations, you will be calculating the acceleration of your cannonball for two different sets of mass and force values. When you have finished with the lesson, you will move on to the boxes free play activity and track the energy needed to knock down all the boxes. Project Outcome: You will be able to explain the relationship between mass, force, potential energy, and kinetic energy. You will use kinematic equations to find the acceleration of a cannonball launched from a catapult. Using what you've learned, you will find the optimal mass, force, and energy needed to knock down a stack of blocks. Learning Objectives: By the end of this lesson, you will be able to: Adjust the mass of a cannonball and the force being used to launch it and understand the relationship between mass, force and energy. Understand the relationship between elastic potential energy and kinetic energy. Understand the relationship between the kinetic energy involved in the launch of a cannonball and the gravitational potential energy that a cannonball gains as it travels higher. Explain the relationship between the law of conservation of energy and the way a catapult launches a cannonball. Use a kinematic equation to find the acceleration of a ball as it launches from a catapult. *Note: The law of conservation of energy and the kinematic equations can be found in the Formulas and More document.

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. Learning Objectives: By the end of this lesson, you will be able to: Adjust the mass of the cannonball being launched from a catapult. Adjust the force applied to a cannonball by a catapult. Understand the relationship between a force applied to a cannonball and its velocity. Understand the relationship between a force applied to a cannonball and the distance it travels. Use the velocity calculated in the Unity editor to determine the acceleration of a cannonball at different points in its arc. *Note: Follow along in the worksheet that can be found under Tutorial Materials. This is also where you can find other important resources like the Formulas and More page.

In this tutorial, you’ll learn about two advanced physics solutions available for projects that use Unity’s Entity Component System (ECS) framework: Havok Physics for Unity and Unity Physics. Important: This tutorial only applies to Unity 2022.2 Tech Stream and beyond, which will be reflected in the tutorial version in early 2023.

In this tutorial we are going to reproduce the Solar System, allow the user to navigate in between planets and learn interesting facts about them. You are in the middle of space, very close to the sun and to what seems a very small planet. When you look at it an information tells you that you are actually facing Mercury, the smallest planet of the solar system. Then instructions start appearing next to your controllers: you can move in space as if you were flying using your joystick. Then you are given the power to trig Mercury’s revolution around the sun by pointing at it. Finally you can be ported to the next planet by pressing a button. You will see interesting facts while you are travelling in space, notice how fast the planets are actually rotating compared to one another and you will realise that some of the distances are really long!
