Sample Short Lab Report By Charles M Borener Jr April 24‚ 2009 Kinetic Friction Experiment #13 Joe Solution E00123456 Partner - Jane Answers PHY 221 Lab Instructor – Chuck Borener Thursday‚ 11 AM – 1 PM Lecture Instructor – Dr. Jacobs Abstract In this experiment‚ we test factors which effect friction. We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface effects friction. We found that the surface area of the block did not change

A hanging mass is tied to a frictionless glider and the mass is dropped. While the glider is being pulled by the mass it is possible to measure to tension force on the rope between the two objects. A motion sensor graphs the movement of the system and from the slope it is possible to calculate the acceleration of both

with minimum friction. A motion sensor will be used to measure various aspects of vector quantities. Description: An Air Track is positioned along the edge of the table. It is a long straight metal beam with many small holes that are roughly each 2mm in diameter. It is positioned at an angle to allow the gliders to glide down the slope. A blower pump is placed under the table‚ and it is connected to the beam‚ which allows air to blow out from the holes to reduce the friction of a moving

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

Coefficients of Friction Discussion: Friction is the force that resists motion and can be determined in either static situations or kinetic situations using the following equation: [pic] Static friction is the amount of friction that resists the start of motion and kinetic friction resists an object’s continued motion. The coefficient of friction depends on a number of factors including surface area and the types of surfaces in contact. The only way to determine a coefficient of friction is experimentally

the window. 4. Look in the yellow data box in the top left corner of the window. Record the mass (m)‚ volume (V)‚ and density (ρ) of the wood block. 5. In the middle of the screen there is a container of water. Record the volume of the water. 6. Drop the wood block into the water. Does the wood block float? Explain why or why not. 7. Place the block so that it is completely submerged in the water. Now what is the volume of the water? By how much did it change? 8. Write a statement

Friction is the force resisting the relative motion of solid surfaces‚ fluid layers‚ and material elements sliding against each other. There are several types of friction: Dry friction resists relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces‚ and kinetic friction between moving surfaces. Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other.[1][2]

Coefficient of Friction- Post Lab Abstract The purpose of the experiment was to determine to coefficient of friction on a block sliding across a horizontal plane‚ and on the same block sliding down an inclined plane. This was done by first testing block‚ and how much weight on a string was needed to move the block at a constant velocity using a pulley system. The block weighed 0.2385 kilograms‚ and needed a hanging mass of 0.05 kg to move at a constant velocity. This means the coefficient of
