Without friction the world would be very different! It would be so strange in a bad and good way.....
For a start, walking would be different because when you put your weight on the foot behind you there would be nothing to stop it sliding. You would fall over and not be able to walk. It would be very hard to get around. You could consider blowing yourself around but it still wouldn't work. Taking in a breath, you would slide forward and then blowing out, you would slide backward!
Buses, cars, trams, trains and bicycles wouldn't work because their wheels rely on
Magnetic transport would have to be created where vehicles would move towards to a magnet that is attracting it. This could be very costly! Brakes would have to be created but they wouldn't be allowed to rely on
Every part on earth that is assembled and kept together with knuts and bolts would fall apart! Can you imagine, building, sky scarpers and famous monuments falling apart because there is no
A lot of sports would be very different. In football the ball would be very hard to grip and kick the ball (if the footballers could move without slipping). The ball would flow like a table tennis ball because of lack of
In watertheme parks water slides would need to be built with more of a horizontal degree otherwise people slide down at the speed somene drops down from a high height! One they do reach the ground, they wouldn't stop so a brick wall would need to be built facing the slide. There could be a lot of bruised bodies involved!
The world would be a very unsafe place for people to live. When meteors enter the earth's atmoshphere there would be know air resistance to break them down. Therfore, the earth would be hit with bigger meteors. This could lead to mass destruction!
Friciton also has its advantages. No engine would ever fail or have to be repaired. Engines would last forever. If there is no
