If the teacher lets go of the string, then the eraser hits a student (or several students) in the classroom. Yet in most cases, the ellipses are very close to a circle since the eccentricities are very close to 0. Navigate to: Review Session Home - Topic Listing. Η = normal force (Greek letter "eta"). The value of g varies with location and so at distances significantly further from the earth's surface, g is reduced and the gravitational force must be computed using a different value of g. D is true; weight and gravitational force are synonymous. The larger the R value, the smaller the acceleration. Overcoming the static friction between two surfaces essentially removes both the molecular obstacles (cold welding between asperities) and, to some degree, the mechanical obstacles(Interference between the asperities and valleys of the surfaces) to movement. The magnitude of the force will depend on the coefficient of kinetic friction between the two materials. So, in most applications, static friction is caused by both adhesion and abrasion of the contacting surfaces. Which of the following statements about friction is true love. Which force causes a rolling ball to stop after a few seconds? Suppose there is an object (block) kept over a smooth surface (friction less surface), Then can the block move if a force is applied to the block(3 votes). When two surfaces are in contact, it may appear that they have a large, well-defined area of contact, but in reality, contact occurs only at certain places – that is, where the asperities of both surfaces interfere. C)It is always object is thrown straight up. If a brick is pulled along a table, the frictional force is the same whether the brick is lying flat or standing on end.
F is true; the acceleration of gravity is the acceleration which is caused by gravity when it is the only force. Some interaction between the asperities of the surfaces will continue, but they won't have enough time to "settle" into one another due to the constant movement. D. ) Define rolling friction. G is false; the acceleration is directed inwards; only the velocity is directed tangent to the circle. C) The direction of the frictional force always opposes the direction of the greatest lateral force. Also, the angle between friction and normal reaction is always 90 degree as friction is always along the surface and normal is always perpendicular to the surface. Kinetic friction is responsible for the wear and tear of machine parts, hence it is important to lubricate the machine parts with oil. Which of the following statements about friction is true story. A. applying lubricant B. using rubber shoes.
For Questions #2-#5, identify the type of force which causes the following bold-faced objects to travel along a circular path. Identify all that apply. The limiting friction is a) Always greater than the dynamic friction b) Equal to the dynamic frict... 16 Which of the following statements concerning friction is true a The | Course Hero. That's because the amount of kinetic frictional force between two surfaces is larger the harder the surfaces are pressed into each other (i. e. larger normal force).
H is true; the acceleration of a satellite is given by the equation g=G•Mcentral/R2 where R is the radius of the orbit. New video tutorials information. What is the coefficient of kinetic friction between the table and the box? Which of the following statements about friction is true brainly. Both are being pulled by the earth due to the gravitational force. On this planet would weightwice as muchA woman whose mass is 60 kg on Earth's surface is in a spacecraft at a height of twice Earth's radius (that is, 3 Earth radii) above Earth's surface. 7 For the following reaction at equilibrium with a ΔH 9044 kJ 4 NO g 6 H 2 O g. 12. Control the two most widely-accepted theories behind static friction have to do with the microscopic roughness of surfaces. Furthermore, if you oiled the concrete (reducing the coefficient of static friction) you would find it to be easier to get the crate started (as you might expect).
Can you explain this answer?. In Example 1: iii) before the fridge starts moving the person must exert a force of 647 N to overcome the static friction, So, the force just after begining of motion would be 800-647=153 N! Answer: In theory, a ball makes point contact with the surface. Effective Resume Writing. B. depends on how massive they are. No friction is when the coefficient is 0 (zero). B. Decreasing the weight on your foot. C. By separating surfaces with a lubricantA student attempts to slide a block down a smooth, dry ramp as shown, but the block does not move. Now that we know the maximum amount of static frictional force is, we know that any force the person exerts below this amount will get matched by the force of static friction. Second law: Force of kinetic friction is independent of shape and apparent area of the surfaces in contact. Your answer: Correct answer: References (click to expand). Questions and Answers.
Will it be easy for Marielle to push the table on a carpeted floor? As such, the person's apparent weight is less than what they are accustomed to experiencing. T the ISS window a few feet away? The moon, however, is still accelerating at the rate any object would have at that distance from the earth. We've got your back. If you reach this force or exceed it, the table will slide.
