For example you could push an empty box easily, but a . By common sense, brick is the roughest and plastic is the smoothest. Friction is created when thingsare pulled past each other. Also, experimental value of is much smaller than . Ad Choices. This will result in greater fluctuation of frictional force and thus greater experimental error. f k = k N. Lab Report On Friction. 0000038220 00000 n It demonstrated that friction is directly proportional to normal reaction but independent of contacting area. Part Two: Force vs. We also experience both of them in the experiment. The coefficients will never be bigger than 1 and the coefficient Friction is a contact force. Effect of applied force on friction Static friction increased with applied force. It's represented by the equation; N = m x g. If the object or plane is inclined at an angle (), the normal . : an American History (Eric Foner), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. motion or attempted motion of one surface across another surface. Diffusion models generate incredible images by learning to reverse the process that, among other things, causes ink to spread through water. To find out the relationship connecting normal force and frictional force acting on an object; take measurements of the coefficients of kinetic and static friction between surfaces to verify that these two figures are autonomous . Other examples of forces are magnetism, gravity and air pressure. Friction Lab Report. A smoother force board can be used to reduce any negative impact that it can have on the experiment. Highlight the constant force portion of your run. Your hands probably got warmer, right? I have used a piece of paper to put rice in plastic bottle until it is about to full. Kinetic friction Once the force applied on a mass exceeds fs,max and the mass begins to move, a kinetic friction force, fk, exists. otherwise. 01/05/2018. First try sliding over a wooden floor with socks and bare feet. Refer to the above explanation. 0000007672 00000 n Slightly more simple and much more powerful is our balloon powered car. We were able to see through the use of F=umg, that the weight of the . Determine the force of kinetic and static friction for the glass surface and sandpapered surface blocks. 0000008914 00000 n The coefficient of the kinetic and static friction depends on the materials used for both contact surfaces. Finally, do you know why a balloon makes a funny noise when you let it go? If you push a toy car it moves, if you push it harder it moves faster. You will submit your completed report. In this lab report it was investigated that, the Kinetic and Static friction force between a steel plank and other materials i.e. Typically the smoother the surface is the less friction. The goals of this lab experiment are to record the kinetic and static frictional forces by the use of a force sensor. But the plan may threaten the fragile landscapeand a tenacious billionaires ambitions. Note the increase in the spring balances reading which indicates the static friction . Required fields are marked *. A. Try pushing the car and comparing with the distance travelled if there is no extra force. Required fields are marked *. The two other types of friction are rolling friction and fluid friction. Our cars travelled a shorter distance when we used the carpet surface than when we used the smooth surface. 17 Limiting static friction is greater than kinetic friction. The normal force of the brick was 1,510 grams and frictional force was 15.6 Newtons. Note that normal force here is also used in step 4 to . 0000001300 00000 n Finally learn all about Newtons famous Laws of Motion! I get: This could be used to solve for the coefficient of friction if you pull at that angle. Watch what happens. A. Your email address will not be published. I know I said it was complicated and that doesn't seem to complicated - does it? Suppose that the opposite hill was horizontal. A Tiny Sun in a Jar Is Shedding Light on Solar Flares. That was the math model for the felt table. 0000011552 00000 n % Friction Force Lab Conclusion After analysis of the data, we found that our hypothesis is true in which the static and kinetic friction is affected by the mass of the object. 0000036797 00000 n The kinetic of the bock on the rug is .41. Try this easy inertia experiment where an object drops straight down into a glass! 1. It is a force that opposes motion or makes it hard for an object to move across a surface. roughness value for the pipe in this experiment is 0.0008. Determine the mean force. 59 5. 0000002328 00000 n . An example of poor friction would be when a 49ers player is not wearing cleats and slips and falls when trying to come to an abrupt stop or change directions quickly. Add 1 block (totally 2 blocks) onto the original one. For younger children, try this fun gravity activity from Inspiration Laboratories. remains constant even the applied force is increased further. This is because there is more friction between the car and carpet than between the car and smooth surface. Learn about reducing friction with this easy Hovercraft. the surface was not moving the block in a constant velocity. Let me look at one more case, and then I will offer things that could be explored. Pop the lid off a bottle with these coin poppers. Forces affect the motion and speed of a football in the game, and different forces can help or hinder motion in the game at different times. Aluminium, Brass, Nylon, Steel.
