friction on horizontal plane experiment

A 3 kg block rests on a rough horizontal plane coefficient of friction 0. Initially, the ball has a northward velocity and is slowing down. Take mean of the readings and calculate coefficient of friction. Three lab partners - Olive N. The iron discs are masses originally used on a balance. Lastly we will use Equation 6.

Glenveau, Glen Brook, and Warren Peace - are discussing an incline problem see diagram. The forces in the x-direction now equal to ma. Analyze each diagram and fill in the blanks. Warren is incorrect because he evidently believes that the normal force is equal to the force of gravity. It is the parallel component of the force of gravity that causes this acceleration. Use the above principles of vector resolution to determine the net force and acceleration of the roller coaster cars. In order to make short, simple film clips, the design does not include precise control of applied force.

Friction Horizontal Plane

Procedure: The link below may be used for the coefficient of friction, although it says Newton's 2nd Law. An object placed on a tilted surface will often slide down the surface. This is the second peculiarity of inclined plane problems. If your refrigerator has a mass of 100 kg, what is the coefficient of friction? The diagram below shows how the force of gravity has been replaced by two components - a parallel and a perpendicular component of force. The other thing to learn was how to calculate the coefficients of friction on a horizontal and elevated plane.

The weight can be resolved into a force down the plane and a force into the plane. A mass of 5 kg lies on a rough plane where the coefficient of kinetic friction is 0. The task of determining the magnitude of the two components of the force of gravity is a mere manner of using the equations. We repeated this a few times and recorded the average. This yields the equation in the absence of friction and other forces Simplifying an Inclined Plane Problem In the presence of friction or other forces applied force, tensional forces, etc. Unless the inclined plane is in a , a usually small amount of is also lost to.

Diagram A The F grav can be calculated from the mass of the object. Discussion: Provide a discussion if necessary. The coefficient of sliding friction between the object and the ramp is 0. Though the math was beyond me, I was still able to understand the formula. Which one of the velocity-time graphs A, B, C, or D would be an appropriate representation of the ball's motion as it rolls across the horizontal surface and then down the incline? The table top is believed to be vinyl.

Inclined Planes

Use the values of M, m, and μ in each row as given on the following Table : In each run row try m such that the block slides at a nearly zero acceleration under 0. Then determine the acceleration of the tire. If you need to apply 200 N, what is the coefficient of friction? The frictional force acting on both the cases will be of same nature Acting in direction opposite to relative motion but the value of forces will vary in both cases. To determine limiting friction, the lateral force was gradually increased. Static friction When a force is applied to a mass in contact with a rough surface and the mass does not move. The force into the plane equals the normal reaction.

Thus, the F frict is equal to the F parallel. The ball rolled off the lane, passed through the freight door in the building's rear, and then down the driveway. Plug this in for the Normal force. Find a the work done against friction. The F grav can be calculated from the mass of the object. Part B, Friction down a ramp: For the second part of the lab, we will take our ramp and place the board on it.

The force of friction is F r and the Normal force is N. We used the spring scale to find the weight of the board in Newtons, and recorded it. Once again, we will record angle β, the height of the board, and calculate the coefficient of kinetic friction using Equation 6. The F grav can be calculated from the mass of the object. Mark a re gion on the ho rizont al surf ace, whi ch is to be us ed for per form ing the experiment because the whole surface is not evenly rough. At this angle the block starts to move with constant speed down the table.

Check Your Understanding The following questions are intended to test your understanding of the mathematics and concepts of inclined planes. The force of gravity will be resolved into two components of force - one directed parallel to the inclined surface and the other directed perpendicular to the inclined surface. The coefficient of friction between the crate and the incline is 0. A 9 kg block lies on a rough plane coefficient of friction 0. This is the same as graphing F versus w , or the same as graphing F k versus N. At rest, the coefficient of static friction is used and if the block is in motion, the coefficient of kinetic friction is used. Thus F norm is equal to F perpendicular.

We will use this and F w,P to calculate the static friction force F f,s. We repeated this a few time s and recorded the average. In this experiment, since the coefficient of kinetic friction is to be measured, constant speed motion of block M requires a zero acceleration. As of June 2005, relativity is 100 years old. Find a the acceleration of the blocks, and b the tension in the connecting string.
