课程名称：事物如何运作：物理学导论 概述：本课程以日常物体为背景，介绍物理学的基本概念。 课程大纲： 1. **课程介绍**：开始学习！ 2. **滑行**：布隆菲尔德教授通过滑板运动探讨惯性原理。静止物体倾向于保持静止，而运动物体则倾向于保持运动。课程讨论为什么静止的滑手会保持静止，为什么正在移动的滑手会继续移动，以及描述滑手流畅、轻松运动的方式。还探讨滑手如何启动、停止或转弯，以及滑行需要冰或轮子的原因。涉及物理概念包括牛顿第一和第二定律及五个物理量：位置、速度、加速度、力和质量。 3. **自由落体**：布隆菲尔德教授通过观察坠落的球体研究重力、重量、恒定加速度和抛射运动的物理概念。 4. **坡道**：布隆菲尔德教授探讨牛顿第三定律相关的物理概念，包括守恒量、支撑力、功、能量和机械优势，通过坡道进行实验。 5. **跷跷板**：布隆菲尔德教授通过跷跷板演示旋转与平移运动的物理概念，牛顿旋转定律，以及五个物理量：角位置、角速度、角加速度、动力矩和旋转质量。 6. **车轮**：布隆菲尔德教授通过对轮子的实验，说明摩擦力的物理概念。 7. **碰碰车**：布隆菲尔德教授分析动量、冲量、角动量、角冲量及势能与力之间关系的物理概念，通过碰碰车进行探索。 8. **期末考试**：进行期末考试以评估学习成果。 本课程旨在让学生通过与日常生活密切相关的示例，理解物理学的基本原理和其在现实世界中的应用。

Description:Start here!
Name:Skating
Description:Professor Bloomfield examines the principle of inertia through skate boarding. Objects at rest tend to remain at rest while objects in motion, tend to remain in motion. Why does a stationary skater remain stationary? Why does a moving skater tend to continue moving? How can we describe the fluid, effortless motion of a coasting skater? How does a skater start, stop, or turn? Why does a skater need ice or wheels in order to skate? Physics concepts covered include Newton's first and second laws and 5 physical quantities: position, velocity, acceleration, force, and mass.
Name:Falling Balls
Description:Professor Bloomfield examines the physics concepts of gravity, weight, constant acceleration, and projectile motion working with falling balls.
Name:Ramps
Description:Professor Bloomfield examines the physics concepts of Newton's third law including conserved quantities, support forces, work, energy, and mechanical advantage working with ramps.
Name:Seesaws
Description:Professor Bloomfield illustrates the physics concepts of rotational versus translational motion, Newton's law of rotation, and 5 physical quantities: angular position, angular velocity, angular acceleration, torque, and rotational mass using seesaws.

Name:Bumper Cars
Description:Professor Bloomfield examines the physics concepts of momentum, impulse, angular momentum, angular impulse, and the relationship between potential energy and force using bumper cars.
