Motion

The technology of moving fast

Motion

Describe this motion. Use as much detail as possible.

Going for speed!

• Top speed of a running human?

Quick History of Motion!

• Top speed of a running human?

24 km/h (for brief period)

Model T Ford

1909 Model T Ford - top speed of????

Model T Ford

1909 Model T Ford - top speed of………….70 km/h

And this was considered frightening!!

Breaking the Sound Barrier

US Marine Fighter Jets 2004

How fast is that?

Breaking the Sound Barrier

More than 1188 km/h !!

How fast is that?

Interesting Facts

•Thrust SSC used 55L / km travelled vs. common car uses 0.07 L/km• Solar car uses no gasoline.

Why did we do this?

• The big idea is that technology of moving has social an environmental impacts – both positive and negative
