Targets

At the end of this unit, you should be able to answer the following questions:

2. How can I build machines so they move the way I want?

2.1 How force be used to move a vehicle?

2.2 How can you build a machine or device that moves on its own?

2.3 What is needed to design a safe vehicle?

2.4 How can ideas be shared and designs be compared to build the best moving device possible?

Devices and vehicles that move have improved very much over the years. If people in the old days wanted to move quickly, they had to do it on horseback or in a horse-pulled carriage. Now, we can get from place to place very quickly. Cars, trains, airplanes, and vehicles of many sorts use various power sources to get us from point A to point B.
