2 friction force lab abstract the purpose of this lab is to help better understand what friction is and how it affects an object's movement close to the surface of the earth. The kinetic force of friction and remained relatively close for the static force of friction the glass block in step 9 seemed to require almost the same amount of force as step 3 and the plain block. The force of friction we will be completing a formal lab report on the force of friction you will record a rough draft of the investigation in your science notebook. Lab: forces and friction p h y s i c s : c h a p t e r 2 - m e c h a n i c a l e q u i l i b r i u m background: friction is a force that holds back the movement of a sliding object. Introduction this lab report is for an experiment dealing with friction on an inclined plane the experiment deals with how friction affects the amount of force that is required to move an object.
Force, we were able to calculate the coefficient of kinetic friction for that trial using equation 8 we started with no mass on the wooden block, then we added a 50 g mass to the block for each successive trial. For example, you could find the friction between wood and steel, wood on wood, rubber on wet pavement, and so on knowing the force required to overcome the friction and the force pushing the object onto the ramp, will allow you to determine the static coefficient of friction. Find that when an object is moved with zero acceleration, frictional force is equal and opposite to the applied force use the formula f = ma to calculate the sum of the forces apply the law of conservation of matter and energy to the movement of a wood block. Hypothesis: the factors of surface, mass, and angle of inclination affect kinetic and static friction 1 attach string between spring scale and wood block zero spring scale 2 place 1000g mass on top of wood block, and place wood block on desk 3 pull from the spring scale at a constant velocity.
A friction tray is pulled from rest using a force sensor until it moves with constant velocity for a few seconds the maximum force on the graph is the maximum static frictional force the force applied to the tray during constant velocity motion is equal to the kinetic frictional force. Friction if there no exists movement among both 1-the the friction force opposes the movement surfaces, there is a static static force of friction, friction of a block which slides on a plane fs that prevents the relative slide of 2-the the frictional force is proportional to the surfaces. Force lab teacher's guide measure the force to move the block of wood and divide it by the normal force (the friction board, wood block, 10 washers, triple. In this experiment we will determine the coefficients of kinetic and static friction for a block of wood on a wood plank, and the static friction coefficients for glass and other materials we will also test the hypothesis that the force of friction does not depend on the amount of surface area in contact.
If the block is at rest, we say that the force of static friction, fs is acting to counterbalance the weight component in the x-direction, and the coefficient of friction is that for the static case, μ s. Using a 500g mass on your block, measure the friction force for an additional two surfaces, lab table and floor summarize your results below: turn your block sideways and repeat with the 500g mass on all three surfaces (wooden plank, lab desk, and floor. With this demonstration you can show static and kinetic friction friction is the force generated between the surfaces of two objects in contact with each other, which opposes any applied force that would accelerate one object relative to the other. Acceleration and kinetic friction coefficients for different materials on wood summary of results: explain the results the thicker/larger the material surrounding the block is, the slower the acceleration.
• use a dual-range force sensor to measure the force of static friction • determine the relationship between force of static friction and the weight of an object • measure the coefficients of static and kinetic friction for a particular block and track. Friction lab friction is a force that occurs when two surfaces touch affects of surface area contact on friction 1) place the bare wood block with the attached. The effect of surface texture is an outstanding science fair project it carefully controls the variables (the things that change in the experiment) by only changing one thing at a time the starting point is always the same. You investigate the force of friction by overcome the friction force and cause the block to the sliding blocks have two types of surfaces: wood and.
I need lab report abt da coefficient of friction of wood & wood lik a complete report, if u did 1 before please send me one more collections hypothesis : for an increase in a normal force, there will be a corresponding increase in friction. Fk is the friction that occurs when two objects are moving relative to each other while they are in contact normal force sliding friction force fk and rolling friction force fr pulling force nf static friction force it experiences friction force the object is moving at constant velocity. Lab report friction essay sample abstract in this experiment, we test factors which affect friction we pulled a wood block across a surface to determine whetherthe surface area ofthe block orthe type ofsurface affectsfriction.
To investigate the affect of the normal force and the angle of the incline on the coefficient of friction materials: inclined plane (wooden board) scale slotted weights weight hanger block of wood with eye screw pulley books. Physics laboratory 5 measuring the coefficients of static and kinetic friction in this laboratory you will measure the coefficient of static and the coefficient of kinetic friction for a wood block and a felt-covered block in contact with a metal track.
• use a force sensor to measure the force of static friction • determine the relationship between force of static friction and the weight of an object • measure the coefficients of static and kinetic friction for a particular block and track. C) friction is a force that opposes motion related sol 41 the student will demonstrate an understanding of scientific reasoning, logic, and the nature of science by planning and conducting investigations. Lab instructor- nathaniel franklin and one is called kinetic static friction is a force wood block 00641. 6 friction, experiment and theory the lab this week investigates the frictional force and the physical interpretation of the coefficient of friction.
