Life Without Friction By: Anthony Cacciato Life without friction would be dangerous. There would be things flying all around and no one would be safe from an airborne bicycle. You would not even be able to stand on your feet. You would not be able to eat or drink. Life with no friction would be deadly. Nothing would be able to sustain life without friction. We would all die if out of the blue friction went away. There are four kinds of friction and they all help us go throughout our daily lives;

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! Having no friction

A World Without Friction (603 Words)Although friction may seem like a minor issue‚ its absence would chance life as we know it. There would be many negative effects of this like not being able to gain traction on any surface and your ipods earplugs always falling out. Also‚ there would be many positive effects‚ such as eliminating the need for coolant in engines and lubricant in machines. Moreover‚ the absence of friction would be both bad and good. Without friction‚ many obvious things which we

FRICTION Friction is necessary for walking due to the following reason‚ As per Newton’s third law of motion‚ (every action has an equal and opposite reaction) we can walk if and only if the ground we are walking on push our feet back with a force. Now‚ as per the third law the ground would definitely push our feet back but if we are walking on a perfectly smooth ground which has no friction our force would simply cancel out the force reverted by the ground and we would fall. If there was no

For an object pulled or pushed horizontally‚ the normal force - N - is simply the weight: N = m g (2) where m = mass of the object (kg‚ slugs) g = acceleration of gravity (9.81 m/s2‚ 32 ft/s2) Frictional Coefficients for some Common Materials and Materials Combinations Materials and Material Combinations Static Frictional Coefficient - μs Clean and Dry Surfaces Lubricated and Greasy Surfaces Aluminum Aluminum 1.05 - 1.35 0.3 Aluminum- bronze Steel 0.45 Aluminum Mild Steel 0.61 Brake material

Life without IT In 21th century‚ people are probably all in Facebook‚ Twitter‚ Weibo‚ etc. Are you spending too much time on your computer? A recent survey shows that about 83% of users said “Yes” and only 17% of users said “No”. Internet influences us so much! But‚ did you ever think that if there haven’t computer any more‚ so what would life be like without the Internet? People may say that:” No‚ it is impossible! Although Steve Jobs died‚ but Apple Company still survives.” So here I want

Experiment 5: Friction Laboratory Report Charles Sanchez‚ Geminesse Sianghio‚ Ferguie Solis Department of Chemistry College of Science‚ University of Santo Tomas España Street‚ Manila Philippines Abstract In this experiment‚ a block of wood is used to observe friction on different surfaces such that an extra weight is also added to the block of wood to measure the same units under the different surfaces. With also the use of lubircant a member of the group was asked to observe the

Friction Definition: Friction is the force resisting the relative lateral (tangential) motion of solid surfaces‚ fluid layers‚ or material elements in contact. Force of friction:- Friction is a force that is created whenever two surfaces move or try to move across each other. • Friction always opposes the motion or attempted motion of one surface across another surface. • Friction is dependant on the texture of both surfaces. • Friction is also dependant on the amount of contact force pushing
