Part One: Scenario Introduction

Why are cars designed this way?

A car generally consists of an engine, chassis, body and electrical equipment

What is the relationship between movement and design?

Motion and design PPT, part 2: research content

1. Advantages and disadvantages of friction

2. What is the purpose of this design?

3. Find good design on your bike

Advantages and Disadvantages of Friction

Discussion: When is friction bad for us? When is it good for us?

When we walk or drive in a car, if the friction is too small, we will slip. At this time, the friction is beneficial. When the machine is running, parts rub against each other and wear, and the friction here is harmful.

Friction is closely related to the world we live in and is everywhere. Things are divided into two. Like many other physical phenomena, friction also has two sides, that is, friction has advantages and disadvantages.

What is the purpose of this design?

In order to move better, people have made careful designs when manufacturing related items. So why are these items designed this way?

Sports and design PPT, part three: expansion and extension

The bicycle was originally invented by a worker guarding the woods in 1817. The bicycles at that time were all made of wood, had no pedals and chains, and relied on both feet to pedal on the ground in turn. It took constant improvements to make the bike what it is today. Bicycles bring great convenience to people's lives.

Motion and Design PPT, Part 4: Class Summary

When an object moves on the surface of another object, there is always friction. There are many good designs on bicycles, which work by increasing and reducing friction and have greatly changed people's lifestyles.
