Recommended: Research about friction

The purpose of the experiment was to determine what factors affect the force of friction through experiments. The objective was to understand how the coefficient of friction is derived from the normal force and force of friction and to determine if the area of contact between the surfaces produces different values for the forces of friction.
Frictional forces are ones that oppose motion when two surfaces are found in contact with each other. Friction is a force acting parallel to two surfaces in contact. If the object is in motion, the friction force always acts opposite the direction of motion. Frictional resistance to the relative motion of two objects is proportional to the force that presses the surfaces together as well as the roughness of the surfaces (Nave, R., n.d.). The force of friction of two objects is usually independent of the area of contact and also independent of the velocity of motion of the objects. The force of friction is given by the equation Ff = (μ)(FN), where μ is the coefficient of friction and FN is the normal force (Jacobs, G., Schulman, J., 2011).

    In the experiment, the experimenter was a 20 year old, female, psychology student at Florida State University. The role of the experimenter was to place the dial caliper on the skin of the participant in various places on the palm, finger, forearm, and back in order to record the amount of area needed between the points of the dial caliper before the participant was able to realize that two points were touching the skin rather than one (Lab Manual). The experimenter also used the method of limits through the use of ascending trials in order to record the participant’s ability to discriminate between the two points on the dial caliper (Lab Manual). Three trails were to be conducted by the experimenter before the experiment was to be considered completed. It was essential to ensure that the two points of the dial caliper were touching the participant at the same time and with the same amount

    In order to begin their outdoor adventure, a skier must first face the forces of static friction. Static friction is the force that keeps the skier at rest. As the skier overcomes the static friction there is a point where the coefficient of friction is greater than that of the kinetic friction that resists the skiers motion. It is clear to see this concept in the figure below.

  • Newton's Three Laws Of Driving

    282 Words  | 1 Pages

    Driving has been around for just over 100 years, but the first thoughts of physics has been around since 400 BC (to be edited ). Driving safety implications have been discussed and improved over the decades as technology begins to leap ahead of its time. According to physician; Newton, there are three laws of motion that is now used in everyday life to try and help prevent deaths due to driving implications. The first law is “An object at rest will remain at rest unless acted upon on by an unbalanced force.” The object, or Car is in motion continues its motion with the same speed and in the same direction unless acted upon by an unbalanced force. The second law is “Acceleration is produced when a force acts on a mass.” While the third Law of Motion is : “ For every action there is an equal and opposite re-action.This means that for every force there is a reaction force that is equal in size, but opposite in direction.”

  • Essay On Force Continuum

    655 Words  | 2 Pages

    The use of force is a heated topic among many people. What is the “Use of Force Continuum”? It is the level of force an officer can use when arresting or subduing a suspect. According to Hicks (2004), “It is considered morally reprehensible for an officer or a sovereign agent to use excessive force without due necessity. However, once the need arises for a proper escalation of force, both the doctrinal theses of just war and the use of force continuum provide for a proper and morally principled use of necessary force” (pg. 255). The use of force continuum was created to guide officers so they are less likely to use excessive force. The officer is expected to use more force than the suspect, but no so that it is deemed excessive. According to Lyman

    In the experiment these materials were used in the following ways. A piece of Veneer wood was used as the surface to pull the object over. Placed on top of this was a rectangular wood block weighing 0.148-kg (1.45 N/ 9.80 m/s/s). A string was attached to the wood block and then a loop was made at the end of the string so a Newton scale could be attached to determine the force. The block was placed on the Veneer and drug for about 0.6 m at a constant speed to determine the force needed to pull the block at a constant speed. The force was read off of the Newton scale, this was difficult because the scale was in motion pulling the object. To increase the mass weights were placed on the top of the ...

  • Summary Of Isaac Newton's Laws Of Motion

    974 Words  | 2 Pages

    The application of force on an object causes an acceleration of that object. Yet, force is not the only factor in the movement, or acceleration of an object. The two main influences on the acceleration of an object are net force and mass. For example, net force is directly proportional to acceleration while mass is inversely proportional to acceleration. Other factors such as the friction, air or fluid resistance, and pressure effect the acceleration as well. All of these factors do not work against or in accordance with acceleration in the same way. Friction works in opposition to acceleration. Friction involves two objects that are in direct contact with on another but are moving in different directions. Involved with friction is air and fluid resistance. Fluid resistance, such as liquids or gases, focuses on when the object is moving in the opposite direction of a fluid flow or through a dense area of fluid. Air resistance involves movement through the air. The most noticeable effect of air resistance is when and object travels into a strong breeze or wind. And finally pressure, pressure refers to an applied force. With pressure you will find that the overall weight of and object doesn’t change no matter how you stand or lay it but you will feel more pressure from that same object depending on the force compared to the amount of surface area. The weight of the object

  • Centripetal Force Essay

    1210 Words  | 3 Pages

    In his Principia, Newton gives definitions related to what he calls “the Mathematical Principles of Natural Philosophy”, the fifth of which is the definition of centripetal force. The given definition of centripetal force is “that by which bodies are drawn or impelled, or any way tend, towards a point as to a centre” (Newton, Def. V). Rather, centripetal force is the force that draws bodies toward a center, rather than away. One way to think about centripetal force is to consider gravity, as gravity is the force that pulls objects down towards the center of the Earth. If an object is thrown into the air, it will return down, for the centripetal force is acting upon it and drawing it towards the Earth’s center. Another way of considering centripetal force is to think of gravity on a much larger scale, for example the gravity that keeps the moon orbiting the Earth. Earth’s gravitational pull towards its center, the centripetal force, keeps the moon from continuing on the path of a right line, and instead keeps it orbiting in a circular fashion. When the moon would other wise move in a straight line, the centripetal force

    When it comes to cars, there are plenty of safety features incorporated by manufactures to ensure a smooth and safe ride. Some of these features seat belts, airbags, and antilock brakes. Nowadays, there have been great improvements to technology within cars to aid in the avoidance of collisions altogether. Examples of these technologies include blind spot detection, backup cameras, 360-degree cameras, and autonomous driving. Many of these newer safety features are there to avoid collisions. However, whenever a collision does occur, there is not much there to protect passengers in the rear of the car. Looking into this, there is evidence that shows that rear passengers do obtain injuries in collisions and pose the threat of contributing to others injuries. So, why are rear passenger airbags not standard in your vehicle?
