of the two friction. Friction is the force that resists relative tangential movement. Its direction is opposite to the relative velocity. Kinetic friction and static friction are two types of friction. Static Friction happens when the two surface in contact remains relatively stationary to each other. It reaches its maximum value before the start of the moving of the object. Kinetic friction is the sliding friction when two contacting surface are in relative motion. Usually, the coefficient of static friction are larger than that of the kinetic friction for the same object. The coefficient…

Purpose: To study sliding friction and to determine the coefficients of static and kinetic friction. Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object. Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is…

Police brutality has become alarmingly prevalent in today’s society, as more and more headliners feature something along the lines of “police brutally kills unarmed African American.” A plethora of names come to mind, including Eric Garner, Michael Brown Jr., and Tamir Rice, who all have been brutally murdered by police who were using excessive force. This exposes the inappropriate and inadequate ways that police handle confrontations with people in the real world. Throughout the chapter,…

Measurement of Static and Kinetic Friction Forces between Wood and a Table Purpose: In this experiment, a spring scale will help calculate the static friction and kinetic friction between a wooden block and table. Several factors impact the amounts of friction, and this experiment examines the factors and how they impact the sliding of the wooden blocks. Surface area of the blocks affect the friction, and the contact between the different surfaces varies for different objects and weights.…

class throughout this whole week was basically to find one suitable objective and that was to determine the friction of four surfaces. It consisted of multiple trials of pulling on a block that was measured at .118 kg, for each specific trial that was conducted. For the block, weights were added on top to determine the friction and how it was affected towards the tension and feel of multiple surfaces that the lab was primarily trying to accomplish. The multiple surfaces were cardboard,…

Experiment 37: Friction Anne Smolinski as910513@ohio.edu Wednesday 11:50-1:40 TA: Sanjoy Sarkar November 11, 2017 Experiment 37: Technical Report ABSTRACT In experiment 37, the friction force is being explained and tested by using a block that is being pulled across a wooden base. Out of the four different types of friction, two will be tested during this experiment: (i) static and (ii) kinetic. Static friction can be defined as the force that resists motion of an object to a surface so…

Protection (Caleb) Laws of motions Fimpact=maaverage=m ∆v/∆t The above equation is rather important. In below, we will talk about the safety measurement in modern cars, and the theory behind of them can be explained by this equation. This equation is derived from Newton second law F=ma, and the acceleration also can be derived to be change in velocity divided by change in time. When collision occurs, the impulse(Fimpactt) is constant, hence the only factor we can change is the time impact…

gives evidence as to how discourse and conceptual development of force can affect two students learning in a physics course. Amy and Deb are two students that were video taped during discussions and activities. There is plenty of evidence of misconceptions…

by force, as it shows the relationship between the force affecting the body, and the movement acquired by the body. Through the study of Newton's first law, we see that in the absence of an effective force on an object or the existence of a group of balanced forces affecting it, This body will be in a state of stillness or regular movement in the straight line. We continue to study the movement of objects when a force affects them, or, in other words when they are under the influence of a group…

derive an equation for the tension in the string (which had a mass attached and was revolved in a vertical circle motion). In order to complete this, the velocity of the mass would have to be calculated using the measured tension, and this value would then be compared to the expected velocity. The second objective of this experiment was to observe how mass, velocity, and radius affect the tension of the string. These objectives were reached in this experiment. Before beginning the experiment, an…
