Key conceptsPhysicsFrictionMotionMaterialsIntroductionHave you ever tried to acquire a running start and slide throughout a smooth, wooden floor while wearing socks? What happens if you attempt the same thing on a carpeted floor or while wearing shoes? The amount of friction in between your feet and the floor surchallenge determines just how well you deserve to slide. Some combinations of surencounters, such as socks on a wooden floor, develop extremely little bit friction. Other combinations, such as rubber soles on a wood floor, create much more friction. In this project you"ll carry out a a lot smaller-scale friction experiment by launching tiny objects along a surconfront through a rubber band also. How perform you think friction will influence how much the objects slide?BackgroundFriction is the force that opposes motion in between two surfaces that are touching one another. Friction is a really essential part of everyday life—without it, you wouldn"t have the ability to walk because your feet would certainly just slip on the floor! Sometimes it is very necessary for surdeals with to have high friction, such as the rubber tires of a vehicle on the road. Other times we desire surdeals with to have low friction, such as as soon as you go dvery own a slide at the playground or sled on a snowy hill. The amount of friction transforms depending upon which materials come into contact with one another.Anvarious other thing that can influence friction on an object is the object"s weight. Imagine pushing 2 boxes—one heavier than the other—made out of the same product. You will certainly need to press harder to relocate the heavier box. This is because gravity pulls dvery own harder on the heavier one, which boosts its friction with the floor. In this experiment you will certainly keep the weight of the objects you usage continuous so that you deserve to test various products without worrying around gravity’s effects.

You are watching: Why is it easier to pull a desk across the floor rather than push it?

Observations and also resultsDid the quarters go farther on the smooth wooden surface or on the carpet?You should have actually found that the quarters went much farther on the smooth wood surconfront than they did on the carpet.

Depfinishing on the stamina of your rubber band also and also exactly how far back you pulled it, you might also have released them all the method off the table or countertop! This occurs bereason there is much even more friction in between the stack of quarters and also the carpet’s turbulent surconfront than there is between them and also the smooth surconfront of the lumber. Due to the fact that tright here is less friction slowing them dvery own, the quarters can slide farther on the wood before they ultimately pertained to a stop.More to exploreEffect of Friction on Objects in Motion, from Science BuddiesFriction Basics, by Andrew Rader at Physics4KidsFight Slipweb page through Friction, from Scientific AmericanScience Activities for All Ages!, from Science Buddies
